Significance

Criterion AThe place is important in demonstrating the evolution or pattern of Queensland’s history.

Riverside Centre (1986) is important in demonstrating the evolution of the built environment of the central business district (CBD) of Queensland’s capital, Brisbane, in the late 20th century. Created as development company Lend Lease’s principal commercial development project for Australia in the 1980s, and designed by renowned architect Harry Seidler AC OBE (1923-2006) of Harry Seidler and Associates, the multi-award winning, nationally recognised Riverside Centre is an exceptional example of a high-quality office tower development undertaken during that period in Queensland. Built at the peak of a boom in office tower construction in Brisbane; designed by one of Australia’s most renowned architects; and incorporating an office tower integrated with a generous, publicly-oriented plaza, and recreational and entertainment facilities, in a riverfront setting, Riverside Centre in its form, fabric and accomplished architectural design, is a distinctive example of a high-rise office tower development from this period in Queensland.

Criterion DThe place is important in demonstrating the principal characteristics of a particular class of cultural places.

Riverside Centre’s office tower is important in demonstrating the principal characteristics of a high-rise office tower built in the late 20th century in Queensland, being an exceptional example of this class of place. This exceptionality is evident in its high-quality, awarded and architecturally recognised design by a renowned architect for one of Australia’s largest development construction companies. The principal characteristics demonstrated at the place are its: prestressed concrete structure, multistorey construction (over 11 storeys) comprising repeated floor plates and a structural service core; modular exterior cladding and glazing; foyer providing centralised access; internal public spaces and surfaces finished with high quality materials, and flexible office floor plates designed to allow for individual tenancy fit-outs. While the tower’s tenancy fit-outs have changed, as designed for in a commercial building of this type, the building retains a high degree of architectural integrity. Designed by renowned architect Harry Seidler AC OBE of Harry Seidler and Associates, the latter of which has remained involved with changes to the place since its completion, and as property developer Lend Lease’s principal commercial development project in Australia during the 1980s, the tower’s outstanding design quality has been widely recognised in Queensland and Australia through ongoing acknowledgement in publications and through accolades given by the architectural profession.

Criterion EThe place is important because of its aesthetic significance.

Riverside Centre, a highly regarded, accomplished development that exhibits cohesive Modernist design principles, is aesthetically important for its high architectural quality.

The visually striking office tower’s beautiful attributes are demonstrated through its well-composed symmetrical and sculptural triangular form, repetitive façade treatments of uniform dimensions, and impressive foyer incorporating modern artwork. The office tower’s centrality to and cohesiveness with the remainder of the place, in particular the surrounding plaza space, is emphasised by the well detailed, high-quality materials throughout (including large expanses of glass and stone), the floor strip finishes that radiate from the office tower’s foyer out through the plaza, and the open setting established by the plaza and low-rise south plaza building. The design, forms and layout of the Riverside Centre have impressive aesthetic qualities, notably through the juxtaposition between the office tower’s form and the expressive curvilinear forms of the cantilevered entrance canopy, south plaza building, and landscaped plaza (including stairs, sinuous walkway canopy, water feature that provides a visual link between the office tower and river, and curvilinear beam), and through the place’s strong visual and physical connection with the Brisbane River. 

Through the office tower’s riverfront siting, distinctive form and surrounding open plaza and low-rise plaza buildings, its beautiful attributes make a notable contribution to the cityscape vista of Brisbane CBD along the Town Reach of the Brisbane River, and from Kangaroo Point and the Story Bridge (QHR 600240).

Criterion FThe place is important in demonstrating a high degree of creative or technical achievement at a particular period.

Riverside Centre, through its outstanding architectural excellence, is important in demonstrating a high degree of creative achievement in the late 20th century. Designed by renowned architect Harry Seidler AC OBE of Harry Seidler and Associates, the qualities of the place have been repeatedly recognised in architectural publications, critique and awards since its construction; most notably with the Royal Australian Institute of Architects (RAIA) (Qld)’s award for Best Building in 1987, the RAIA’s national Sir Zelman Cowen Award for Public Architecture in 1987, the RAIA (Qld)’s Robin Dods Triennial Medal in 1989, the First Prize in the Marble Architecture Awards (Carrara, Italy) in 1989, and the Australian Institute of Architecture (AIA) Queensland Chapter’s ‘25 Year Award for Enduring Architecture’ in 2011. These awards acclaim the Riverside Centre's: outstanding architectural quality; the office tower’s refined and rational design (including its form, scale, size, materials and structural system); impressive foyer with quality materials; considered responses to climate (including exterior sunshades tailored to orientation, and sky gardens); well-ordered urban design and the generous, open space of the plaza layout; and the highly-regarded physical and visual connection of the place to the Brisbane River.

History

Completed in 1986, Riverside Centre was designed as development company Lend Lease’s principal project for the 1980s. It was built during a boom in office tower construction in Brisbane, including the emerging heart of the financial district between Queen and Edward streets. Designed by internationally renowned architect Harry Seidler in 1983, the $200-plus million development included a 40-storey office tower, a plaza providing open-air public space with access to the Brisbane River, and entertainment, food and transport facilities. Riverside Centre became home of the Brisbane Stock Exchange, with a purpose-built bourse on the lower office levels. It also became a popular centre for recreation, as Brisbane’s social focus was increasingly oriented towards the outdoors and the river.

Growth of the Brisbane Central Business District

Part of the traditional lands of the Turrbal and Yuggerah people, the non-indigenous occupation of Brisbane began with the Moreton Bay Penal Settlement (1824), before the area was opened for non-indigenous settlement in 1842. Established on the site of the former penal colony, Brisbane then was encircled by two reaches of the Brisbane River, and was declared a port of entry in 1846. It became the capital of the colony of Queensland in 1859, and was proclaimed a city in 1902.

The expansion of the colonial economy and related shipping activity from the 1840s shaped the need for buildings in Brisbane to house office-based work, banking, and insurance.[1] Brisbane developed as Queensland’s commercial and financial centre and its major port, hosting the headquarters for the colony’s principal businesses, financial institutions, shipping companies and government. Its buildings were erected largely in economic boom periods in the central business district (CBD) in the 1860s, the 1880s and the 1920s. These were clustered into precincts, with most of the government buildings erected along George Street, the retail and financial district stretching down Queen Street, and a shipping, wharf, and warehouse precinct along the Town Reach, the riverfront between the Botanic Gardens and the Kangaroo Point bend.[2]

In the early 1920s, most of the Brisbane CBD’s buildings reached only one or two storeys (including residences), with warehouses up to three and four storeys, and a small number of commercial buildings extending up to eight storeys (such as Perry House, built in 1910).[3] The 1920s boom brought taller buildings, but in 1926, building heights were restricted to a maximum of 132ft (40.23m), or eleven storeys.[4] Accordingly, financial buildings along Queen Street were erected up to ten storeys during the 1920s and 1930s, but much of the CBD’s built stock remained lower scaled[5] By the time construction work was halted for the outbreak of World War II, the Brisbane City Hall clock tower (278ft) was the tallest structure in the CBD.[6]

The rise of the office tower

The second half of the twentieth century brought considerable change to the Brisbane CBD. Brisbane’s population climbed to half a million in the late 1940s, overtaking Adelaide as Australia’s third largest city.[7] The CBD’s first postwar office building, an eleven-storey curtain wall modern office block for MLC, was completed in 1956, though a credit squeeze limited further construction for the next several years.[8] Shopping centres were built in the suburbs and shipping facilities moved further downstream towards the river mouth, leaving the CBD’s traditional retail and wharfing precincts in decline.[9] However, Queensland’s mining and property industries boomed in the 1960s and 1980s, encouraging investment into the state. This, accompanied by governmental encouragement of private enterprise, favourable development policies and the removal of building height restrictions under Brisbane’s first Town Plan in 1965, increased business in Brisbane’s CBD.[10] High-rise offices were constructed across the CBD to meet demand from Queensland’s growing tertiary industries, particularly finance (including banking, insurance and assurance, and merchant banking); government; and to serve as state headquarters for Queensland’s agricultural, pastoral and mining companies.[11]

The high-rise office tower emerged as a building typology during the late 19th century in Chicago and New York in the United States of America, where architects and engineers manipulated the metal frame, electric lift, and air-conditioning systems to establish tall buildings for work spaces.[12] During the mid-to-late 20th century this building type was increasingly constructed in Australian cities and continuously evolved with the established building tradition.[13] While there are numerous descriptions of the height associated with the term ‘high-rise’ worldwide, it is most often based on building codes and fire regulation applicable in individual geographical locations.[14] With the removal of height limits in the 1965 town plan, Brisbane’s high-rises rose above 132ft (40.23m; approximately 11 storeys).[15]

High-rise office towers from the late 20th century typically featured a structural frame of metal, reinforced concrete or pre-stressed concrete; repeated floor plates with spaces for desk work; entrance foyers for centralised access; and vertical cores that usually assisted in withstanding lateral forces such as wind and included: lifts, stairs (for fire egress), toilets and service ducts.[16] Most buildings of this type adopted the ‘shell and core’ concept, where the exterior design of the building was highly-specified, and the interior spaces were standardised and flexible (largely open-plan), allowing for tenant-specified individual fit-outs and periodic refitting.[17]  Semi-public spaces that were at the forefront of user-experience, such as entrance foyers, lifts, boardrooms and restaurants, were often of a more refined architectural finish.[18] During the 1960s and 1970s, heavy concrete curtain wall cladding was popular, and from the late 1970s, building designs increasingly featured flat, sleek and reflective surfaces, including all-glass facades or polished marble or granite.[19] The curtain wall cladding was often modular and prefabricated.[20] Sun control was handled in various and evolving ways, such as structural frame projections, external shading devices (including external hoods, screens, egg-crate sun breakers (horizontal and vertical flanges positioned in a square grid), or sun-blades), reflective glass, or interior blinds.[21]

Between ninety and one hundred high-rise offices were constructed in the Brisbane CBD between 1965 and 2000, with more in near-city suburbs.[22] The first building to claim a height over eleven storeys, the 16-storey Pearl Assurance office, was completed in 1966. The next several years brought a series of ever-taller buildings, from the 20-storey Manufacturers Mutual Insurance Building (1967);[23] to the 23-storey Bank of New South Wales (1970); the State Government Insurance Office (1971); the first building over 60 metres, 167 Eagle Street (1973); and a series of high-rise towers for government, mining, investment, financial and insurance groups completed by 1976, mostly designed in the ‘international modern’ style which dominated high-rise office design in Australia.[24] The most intense growth in the CBD occurred in a five year period in the mid-1980s, when development underpinned by a resources boom triggered extensive office building construction.[25] Almost one million square metres of floorspace was constructed in Brisbane during this time, significantly reshaping the city’s appearance.[26]

The former wharf and warehouse precinct along Town Reach was a focus for high-rise office development. It held the city’s first high-rise and two of the tallest buildings (167 Eagle Street, 1973; and AMP Gold Tower, 1978), as well as several more modest high-rise offices. The construction of the city’s first fully glass-clad ‘Gold Tower’ for AMP in 1978 gave rise to the precinct being called the ‘Golden Triangle’, and its reputation as a desirable office location.[27] Office towers were erected in the Golden Triangle and named for the highest-paying lessee, ranging in scale from the 18-storey, $9 million GWA House on Market Street (1982), to the record-setting $60 million AMP Blue Tower (1984), a 35-storey ‘technologically-advanced marvel’.[28] The Golden Triangle became the CBD’s acknowledged financial heart[29] as the precinct became home to a series of ‘gleaming office towers’.[30]

The 1980s also saw the emergence of office towers described in real estate parlance as ‘blue chip’, ‘premium’ or ‘prime’, responding to demands from the financial and professional sectors.[31] Notable amongst these were the Gold Tower, its twin ‘Blue Tower’ (1984), the CML building on Queen Street (1984), Capital Centre on Adelaide Street (1984), Central Plaza One and Two (1987-88), and Waterfront Place (1990).[32] In a single decade (1979-1989), Brisbane climbed from one of the least expensive cities for office rentals in the world, to 15th in the world for premium office buildings, and 24th in the world for office rentals overall.[33]

The long boom of Brisbane’s office towers ended abruptly in 1990. Projects were put on hold as the Queensland economy began a downward turn, and Australia entered a recession. Several proposed major office towers projects were postponed or abandoned. Strong building activity did not recommence for another decade.[34]

Lend Lease, Harry Seidler and Associates, and Riverside

In 1979, development company Lend Lease began investigating sites for a landmark project.[35] Lend Lease, established in 1958 by Dick Dusseldorp, was one of Australia’s largest development construction companies,[36] responsible for housing, retail, and commercial construction across Australia in the second half of the 20th century. The company formed a development triumvirate with construction and engineering business, Civil and Civic, and financial enterprise, General Property Trust (GPT),[37] allowing it to undertake significant projects.[38] The company had built two ‘landmark’ or statement high-rise projects in Sydney: Australia Square (1968) and the MLC Centre (1976), both designed by architectural firm Harry Seidler and Associates.[39]

Encouraged by Queensland’s economic progress and forecasts for further growth, the company focused on the Brisbane CBD for its 1980s landmark.[40] The company’s attention was drawn to the burgeoning financial centre, where, by 1979, office towers lined the streets between remnant shipping company and government maritime buildings. Though construction had shifted towards the river, development on riverfront sites had been limited by a proposed riverfront road.[41] The disused wharves of the Australasian United Steam Navigation Company (AUSN), Thomas Brown and Son, and Nixon Smith remained in situ, used for carparking.[42]

A Lend Lease subsidiary, Lend Lease Developments, began to acquire multiple sites fronting Eagle Street and the river.[43] In June 1981, the company announced that it had received approval in principle for a multi-million dollar riverfront development project.[44] After a year of planning, revisions, and land purchases, in August 1982 the Courier Mail published plans for ‘Riverside Brisbane’, Lend Lease’s $200 million development for its 1.4 hectare Eagle Street site.[45] ‘Riverside Brisbane’ was proposed to include an office tower, shops, residential apartments, plazas, promenades, a marina, an ‘historic precinct’ for the soon-to-be-demolished Wool Exchange, and a section of the riverfront road, a condition of the development’s approval.[46] The company highlighted its desire to create a ‘total pedestrian environment’ with tourist facilities including restaurants, taverns and bistros ‘to give the complex life after business hours’.[47]

Over the following year, Lend Lease continued to accumulate land, as well as leasehold over a laneway (Parbury Lane), and the AUSN’s No. 11 and No. 13 wharves within the river.[48] Having acquired control over a 2ha site, Lend Lease engaged architect Harry Seidler to redesign the Riverside project in August 1983. Austrian-born Seidler had already achieved significant renown as an architect in residential and commercial designs, including the award-winning Rose Seidler house (1950),[49] Australia Square,[50] MLC Centre, the Australian Embassy in Paris (1977), and the soon-to-be-completed Hong Kong Club Building (1984). He had received multiple awards from the Royal Australian Institute of Architects, including its highest honour, the Gold Medal, in 1976, for outstanding achievement in architectural design and the promotion of architecture and the profession; and received an OBE for his services to architecture in 1972.[51] His firm, Harry Seidler and Associates (established 1960), had been working with Lend Lease almost since its inception, designing apartment buildings (Ithaca Gardens (1960) and the controversial Blues Point Tower (1961)),[52] recreational facilities (Thredbo Ski Lodge (1962)) and commercial buildings (Australia Square and MLC Centre, the former of which was considered ‘one of Australia’s most important works of the postwar period’).[53]

Influenced by international architects, artists and designers Walter Gropius, Oscar Neimeyer, Marcel Breuer and Josef Albers, Seidler’s designs strongly adhered to principles of modernist architecture. Modernist architecture developed in pre-World War I Europe and gained popularity in Australia after WWII. Notable for a rationalisation of planning, emphasising clarity and simplicity of form and detailing,[54] the style had been adopted in Queensland in a variety of residential, religious, public, and commercial buildings.[55] Seidler was one of the country’s foremost postwar architects to design in the modernist style.[56]

As in earlier projects, Lend Lease allowed Seidler creative freedom to achieve the design requirements.[57] While the facilities remained relatively consistent with the earlier design, Seidler’s design for Riverside reenvisaged them into an integrated plan adopting his architectural philosophies,[58] similar to his designs for Australia Square and MLC Centre.[59] At the centre of the site was a triangular-shaped office tower, set in an open-air plaza, with surrounding low-rise retail, entertainment, and commercial facilities. The buildings featured clean lines and limited ornamentation. The positioning of the office tower, set back on its plaza, was in accordance with modernist design principles,[60] while the curved form and position of the low-rise buildings within the plaza provided an organic-shaped contrast to the geometry of the tower.

The office tower was 40 storeys, including two basements for carparking.[61] It was positioned in line with the city street grid, providing views along Eagle Street and down Elizabeth Street, while its triangular shape allowed two-thirds of the office’s full height glass windows to face the Brisbane River. Aluminium sunshades, fitted on two sides of the building, were designed to address the different angle of the sun on each elevation, but minimise disruption to the views. Recessed sky terraces interspersed across two sides of the building broke up any repetition. The tower was to be clad in a cool pearl-coloured granite, providing a contrast to the glass towers emerging along Brisbane’s skyline.[62]

The main entrance to the tower building, from Eagle Street, was covered by a glass canopy with gathered columns.[63] These were braced by radiating concentric floor ribs, providing ornament as well as being a structural necessity. This led into a four-storey (15m), glass-walled foyer, with exfoliated black granite-lined floor with strips of travertine.[64] The foyer was ceiled by external support concrete beams brought together in a decorative web pattern, designed by Mario Desideri, successor to renowned Italian engineer Pier Luigi Nervi.[65] Services were located in the building’s core.[66] The height of the building required three banks of lifts, with changeover levels, and a separate lift to the two basement carpark levels. The tower contained 36 levels[67] of offices to be leased to commercial tenants. The column-free, open floor plates allowed for fit-outs to be adapted to a tenant’s preferences, and easily altered when turnover occurred. The tower’s floor size (1,500m2) was unusually large, allowing larger firms and businesses to consolidate their operations into a smaller area, providing advantages in improving communications and reducing costs.[68]

Plans for the plaza changed slightly after an additional land purchase was settled in 1984.[69] A 350-room hotel building was postponed for a later stage,[70] while a six-storey office building morphed into a single-storey commercial structure; and a low-rise riverfront residential apartment building was removed.[71] The latter provided additional space for the open plaza, which occupied over half of the site,[72] providing unimpeded views and direct public access to the river. It was enhanced by landscaped gardens, trees, and a jet fountain water feature which pooled on each side of the triangular building’s riverside face, and cascaded down the terraced plaza towards the river.[73] Stairs and ramps (called by Seidler, stramps) carried pedestrians down to the riverfront, where a promenade extended along the site’s 180m river frontage, lined with bollards linked by nautical chains, purpose-designed by the architectural team.[74] A ferry terminal and marina, which led off the promenade, provided public and private access to the site from the river.[75] Views from the plaza took in the sweep of the Town Reach, Kangaroo Point Cliffs and Story Bridge, framed by a curvilinear beam across the step-ramp and cascading fountain.[76]

The public plaza was of particular significance to both Seidler and Lend Lease. Lend Lease had long envisaged the waterfront public space as an important part of the landmark project, while for Seidler, the provision of public space in the creation of an urban environment[77] was an essential part of his design.[78] Above all, Seidler was quoted as saying, Riverside would be a place for people: ‘“It’ll be a meeting place, a shopping place, an eating place – a landmark for decades to come.”’[79]

Construction of the Riverside Centre

Site work was underway on the project by April 1984, when the name ‘Riverside Centre’ was publicly used.[80] Construction work officially began in June 1984, and was launched with a flag-raising ceremony featuring the Queensland Theatre Orchestra, two tonnes of fireworks, a 400-person cocktail party, and a two-hour riverboat dinner cruise for one hundred children from the St Vincent’s Home for Children.[81] In accordance with its intention for Riverside Centre to be its landmark development of the decade, Lend Lease promoted the building project heavily, including addressing any potential issues with an immediate public relations campaign. When a series of blackouts affected CBD buildings in March 1985, Lend Lease advertised Riverside as ‘Brisbane’s Most Prestigious Powerhouse’, promoting it as ‘the only major centre with 4 generators capable of supplying 100% power to the whole building… a technological masterpiece’.[82]  

Civil and Civic began construction of the office tower in 1985, progressing at an average of one floor every four days.[83] The core was built first using a jump-form technique, and the concrete tower was poured in place, with prestressing occurring on site.[84] Economic considerations built into the design helped to speed construction and minimise costs; the corners of the tower’s triangular shape were rounded to simplify the design, and  repetition of elements allowed for uniformity of structural beams.[85] Pylons were laid into the river in March 1985 for the riverfront road, which was to run under the development, but within months, the requirement for the road had been scrapped.[86] The topping off was celebrated in October 1985 with full-page newspaper advertisements congratulating the workers, and a large party was held.[87] The following twelve months was spent finishing the building, plaza and low-rise buildings, installing office fit-outs, landscaping, and trees on the terrace gardens.[88]

The cost of the project allowed for high-quality materials, finishes, sculptures, and artwork. A sculpture by artist Norman Carlberg, ‘Winter Wind’, a 10m repetition of a single quadrant shape in white-painted steel was commissioned and installed in the main section of the foyer (from the Eagle Street entrance), and tapestry artwork by Alexander Calder (a favourite artist of Seidler, whose work had been used in earlier Lend Lease developments) along the travertine walls of the lift core on the north and southern sides of the foyer.[89] The architectural team from Harry Seidler and Associates, including Harry Seidler, Henry Feiner, and Greg Holman, designed minutely detailed interior fittings in what was referred to as ‘a “ridiculous amount” of design creativity’, including purpose-designed light-up elevator buttons, ashtrays, and skirting ducts.[90]

Around $15 million was reportedly to be spent on interior fit-outs for tenants in the four month period leading up the building’s opening, ‘the same efforts needed to build a small city high-rise’.[91] The initial fit-out included a purpose-designed facility on the fifth and sixth floors for the Brisbane Stock Exchange, the building’s anchor tenant, featuring a trading floor, theatre and a mezzanine over the foyer, and no external windows. Pre-commitment tenants were able to specify their own fit-outs from the outset, including stairs between levels. By its opening Riverside Centre had over 75% pre-committed tenants (a high figure for the time).[92]

The plaza was also minutely detailed, with granite seating, signs, waste bins; porfido (porphyry) plaza paving; and the Riverside Centre name and logo across the site.[93]  The plaza buildings included a single storey commercial building on the northern side close to Eagle Street (‘North Court’ or Northwest Plaza), and Michael’s Riverside Restaurant on the riverside, cantilevered over the river (Northeast Plaza). On the southern side, a single-storey retail court near Eagle Street flowed into a two-storey building fronting the river promenade (South Plaza). The lower floor held ‘On the Deck’ eateries and shops, while on the upper floor was ‘Friday’s’, with outdoor bar terraces featuring finishes in imported granite and overlooking the plaza and river.[94] The plaza buildings’ financial, retail, care services and eateries would not only serve Riverside Centre workers, but also the 14,000 to 20,000 office workers employed throughout the Golden Triangle, where these services were limited.[95] Lend Lease aimed to provide a range of eateries, from restaurants for business lunches to quick dine-in or casual takeaway, to Friday’s, catering for after work crowds.[96] Retail fit-outs were by Aspid International.[97]

Climatic considerations had been woven through the design, and were implemented during the construction. The use of sunshades (installed in 1986 as the building’s ‘eyelids’) and granite facing, instead of a glass-faced facade, reduced heat load on the building.[98] Hailstorms in January 1985 led to extensive testing to ensure the sunshades would withstand future storms, and a year-long study was undertaken to determine individual angles of installation.[99] The glass canopy over the main entrance and a wavy canopy connecting the tower’s north-eastern entrance to the northern plaza buildings provided shelter from subtropical downpours.[100] The length of the project allowed time to study and eliminate wind tunnels in the plaza, and to best position outdoor eating areas for summer shade and winter sun. This, Lend Lease Development hoped, ‘would ensure that people would be drawn to the plaza not only because of its facilities and views, but because it offered the right atmosphere at the right time of year.’[101]

Tenants moved into Riverside in September, before celebrations to mark the building’s opening began on 1 October 1986.[102] The fireworks displays, hot-air balloon launches and parachutist drops were covered in newspapers and on the evening television news.[103] Ten days of celebrations followed.[104] The tower was intended as an ‘intelligent building’, with advanced technology installed.[105] On completion, the building was transferred to GPT. The official handover ceremony included using the tower’s advanced technology to turn on the top floor air-conditioning from Sydney. [106]

Architectural recognition

Riverside Centre drew immediate acclaim from the architectural world. Covered in Australian and international architectural publications,[107] it was awarded the Royal Australian Institute of Architects’ (Queensland Chapter) best building award in 1987 (joint winner with the State Works Centre (no longer extant)), which acknowledged the ‘superbly detailed, sophisticated’ tower as ‘the central focus of a well ordered urban precinct which provides the city with a fine example of the potential to be gained from positively relating development to the river.’ While the entrance lobby was ‘somewhat overwhelming, but impressive,’[108] the incorporation of water in the pedestrian concourse, art works in the lobby and well selected furniture contribute to an overall feeling of good taste’.[109]

The national architectural body, the Royal Australian Institute of Architects, awarded Riverside Centre the Sir Zelman Cowen Award for non-residential works in 1987.[110] The Sir Zelman Cowen award was generally awarded for public architecture, but Riverside Centre’s public pedestrian plaza set it apart from other private developments. As the jury noted, Riverside Centre reflected Seidler’s approach to high-rise projects, where ‘the use of a high-rise solution justified by the provision of open space for people at the foot of his buildings…providing a community attraction for all those who do not directly use his building, but seek shelter in the city oasis he creates’.[111] While the project was not ‘anything radically new’ for Seidler and his ‘already well-honed skills’, the project’s scope and size ‘allows his very simple clean cut design approach to make an impact by its repetition over a large area and a number of small buildings at the concourse level’.[112] In addition to the ‘interesting architectural solutions’ of the building itself (including its triangular shape, clean building lines, the texture provided by the aluminium sunscreens, and the ‘imagination and attention to engineering detail’[113] expressed in the foyer’s ceiling), the ‘impressed jury’ noted Riverside Centre’s ‘unique relationship to the Brisbane River’, linking the tower to the river and making the river ‘not only part of the building, but a focal point.’[114]

Renowned British historian of modernist and contemporary architecture, Kenneth Frampton, authored a publication on Riverside Centre in 1988. ‘In many respects Riverside Centre represents a consummate synthesis of everything that Seidler has projected and realised over the past twenty years’,[115] Frampton wrote, marvelling at the ‘straight-forward logic with which Seidler has arrived at the parti for Riverside Centre.’[116]

A balance is established between the twin dialogical themes that inform the entire work; on the one hand, the opposition between tectonic and organic morphologies, on the other, the play between symmetry and asymmetry, which permeates the entire site and which will be so much more dynamic as a dialogue, once the project is complete.[117]

In a later publication, Frampton highlighted the vertical juxtaposition of the tower against its horizontal length; the play between symmetry and asymmetry of the structures across the site, and ‘the contrast between the tectonic logic of the skeleton structure and its plastic amplification as an isostatic form.’[118]

Months after the completion of Riverside Centre, Seidler was named a Companion of the Order of Australia (AC) for the advancement of architecture.[119] He and the architectural firm went on to design a number of office towers around Australia, including Grosvenor Place, Sydney (1988); Shell House, Melbourne (1989); Capita Centre, Sydney (1989); and QV1, Perth (1991).[120] Frampton and some later commentators, including Australian architect, academic and author, Jennifer Taylor, considered Riverside Centre a standout amongst Seidler’s later office tower developments: an evolution in Seidler’s work incorporating the landscape concepts of South American architects Burle Marx and Niemeyer and notions of ‘isostasis’;[121] Seidler’s solution to the problems of urban space in Australian architecture;[122] a demonstration that it was ‘still possible to continue with a viable culture of modern architecture’;[123] and ‘a notable urban achievement, which, besides being an accomplished work of architecture, regenerated an entire urban precinct and turned the focus of a city towards its river with unprecedented generous riverside plazas.’[124] In 1996, the Royal Institute of British Architects awarded Seidler the Royal Gold Medal for Architecture, one of the highest honours for architects in the world, for his body of work. In his accompanying speech, Seidler referenced Riverside Centre (alongside other projects).[125]

In 1988, Riverside Centre received further recognition as the joint winner of the Robin Dods award (a triennial award by the RAIA Queensland Chapter for excellence over a three-year period), as, according to the judging panel, it ‘sets an incredibly high standard as well as giving Brisbane a magnificent riverfront public space.’[126] The building received first prize in the 1989 Marble Architectural Awards in Carrara, Italy.[127] In 2011, the Queensland Chapter of the Australian Institute of Architects (AIA) awarded Riverside Centre its Enduring Architecture award. This award is given to a structure at least 25 years old, of outstanding merit that, considered in a contemporary context, remains important as a high quality work of architecture.[128] Riverside Centre was also recognised as significant 20th century architecture by the AIA at both State and National levels.[129]

Office impact

Riverside Centre’s opening had an immediate impact on Brisbane’s commercial office market. Thanks to the availability of river views across two-thirds of the tower,[130] Riverside commanded some of the highest rents in Queensland – $444 per square metre in 1988 – and was credited with increasing rental levels in prime office market from 15% to 20%.[131] The presence of the Brisbane Stock Exchange in the tower encouraged legal, accounting and stockbroking firms, including some establishing Queensland offices for the first time.[132] The prestige of the building was also acknowledged as a draw for some tenants. The Queensland Division of the Building Owners and Managers Association awarded Riverside Centre a special citation for its ‘outstanding contribution to the city by establishing Brisbane as a mature commercial centre and for its civic and environmental design’.[133] Developers undertaking other large office tower developments in the Golden Triangle acknowledged the new standard the project had set for the ‘top end of the market’,[134] while the Queensland Governor stated in 1988 that Riverside Centre ‘has brought a whole new dimension to the standard of accommodation to which professional and commercial organisations may aspire.’[135]

Though a private development, Riverside Centre was highlighted by state and local governments as evidence of the city and Queensland’s growth and development. It was promoted by successive Brisbane Lord Mayors as part of Brisbane’s diamond jubilee and the Shine On Brisbane campaign;[136] in the United States as a technologically ‘intelligent’ building;[137] and was featured in a Queensland Government television programme in the late 1980s.[138] Its completion, alongside that of the Brisbane Transit Centre in Roma Street, prompted ‘a school of thought… that Brisbane is capable of being the business capital of the southwest Pacific by the year 2000.’[139]

The scope and cost of the office tower development project was significant. The size of the site – 1.4ha – dwarfed most of the sites on which Brisbane’s other office towers were erected,[140] and for a brief time it was the tallest building in Brisbane (though its successor was under construction when Riverside opened). At a reported cost of $200 million, Riverside Centre was the first office tower development in the CBD to cost over $100 million, and was significantly more expensive than the record-setting AMP Blue Tower, constructed two years earlier for $60 million.[141] Riverside Centre remained one of the few 20th century office tower developments in the Brisbane CBD to cost over $100 million, with only two further projects, both neighbours to Riverside Centre, before the economic recession of the 1990s: the two-tower Central Plaza complex designed by Japanese architect, Kisho Kurokawa, and Queensland architectural firm, Peddle Thorp, opening in two stages; and Waterfront Place, designed by Perth architectural firm Cameron Chisholm Nichol, and also opened in two stages (Eagle Street Pier, 1989; Waterfront Place, 1990).[142]

Public impact

The public aspects of the development were also quickly appreciated, as Riverside Centre began to draw people to the city after working hours. Ferry services started at the Riverside terminus, which replaced the Creek Street ferry stop, in October 1986, bringing city workers and visitors to and through the site. A high-speed service running to the University of Queensland started the following year, and City Cats served the terminal from 1996.[143] By 2003, Riverside was Brisbane’s busiest ferry terminal, serving 400,000 passengers annually.[144] The riverfront promenade was incorporated into a bikeway that was extended along the riverfront in the mid-1990s, providing riverfront access to the site for pedestrians, cyclists, and commuters.[145]

The South Plaza eateries were advertised to the public to ‘come and enjoy’ while ‘soak[ing] up the feel of the tropics under the sun and the palms, beside the river.’[146] Friday’s and Michael’s became popular venues for Brisbane residents – students, those celebrating special events, and office workers – over the following years.[147] Building management and tenants hosted art displays, showcase exhibitions,[148] and fundraising events in the foyer;[149] and a viewing gallery in the Stock Exchange fit-out was open to the public.[150] In May 1987, the recently-formed ‘Cats Tango’ craft markets were moved to the Riverside Centre plaza. Renamed the Riverside Markets, the Sunday event proved a huge attraction, bringing large numbers of suburban residents and international tourists to the site on a weekend for the next 22 years.[151]

Riverside’s development, and the intense change in the CBD’s physical fabric, was accompanied by significant social and cultural change.[152] As Brisbane’s population reached over one million people in the early 1980s,[153] the city prepared to host two major international events: the Commonwealth Games (1982) and the World Exposition 1988 (colloquially Expo 88). ‘Shine on Brisbane’, ‘Image ‘82’ and ‘Image ‘88’ campaigns encouraged beautification in and around the city, and the city was promoted internationally (particularly in the United States) amidst a push to encourage international tourism.[154] Pedestrianism was improved in the city centre with the construction of pedestrian bridges crossing Anzac Square (1982) and the opening of Post Office Square (1984).[155] The Queen Street Mall, opened in two stages (1982 and 1987) both improved pedestrianism and enticed shoppers to return to the city. Legislative change in the late 1970s provided for Friday night shopping in the city and Sunday trading in hotels. Riverside Centre was part of Brisbane’s identity shift in the 1980s, providing facilities for al fresco dining before it was incorporated into the Town Plan in the 1990s; and popularising open, riverfront gathering space with markets and promenades in the leadup to Expo 88.[156]

Riverside’s opening also coincided with renewed public interest in the Brisbane River. A hub for commerce, transport and recreation from the mid-19th century, the Town Reach of the river had fallen out of favour in the second half of the 20th century, as wharves and bathing facilities were removed, and the Riverside Expressway cut off public connection to the riverbanks. Only a promenade through the Botanic Gardens provided unimpeded access to the river. From the late 1970s, river management, development and clean-up committees had emerged, urging an end to dredging, cleaning up the river, beautifying and managing development on riverbanks. Brisbane City Council declared 1987 the ‘year of the river’, creating river management studies and strategies, and a riverfront walk was opened through the mangroves. Increasingly, images of Brisbane portrayed the river from the Story Bridge or Kangaroo Point, with Riverside Centre at their centre. The relocation of the Customs House ferry terminal to Riverside Centre placed the new office tower at the heart of river transport into and out of the city. In coming years, as Brisbane’s ‘River City’ identity emerged, Riverside Centre’s restaurants and terraces became a popular gathering space for New Years’ Eve fireworks, special events such as the arrival of the ‘tall ships’ in 1987 and 2001, the docking of the Endeavour replica in 2011,[157] and the annual Riverfire festival fireworks displays.[158]

Riverside Centre in the 21st century

Riverside Centre has continued to attract and retain high-profile tenants to its office tower, including stockbroking firms, banks, accountants, legal firms and in 2023, the organisers of the Brisbane 2032 Olympic and Paralympic Games.[159] The tower’s anchor tenant, the Brisbane Stock Exchange, was replaced by the Australian Stock Exchange (ASX) in 1990, remaining a significant financial centre in Brisbane until 2005.[160] As home of the ASX, the building was a target for protests in 2001,[161] and Richard Branson launched Virgin Blue onto the ASX from the building’s foyer in December 2003.[162] In 2006, the twenty-year old office tower was fully leased, and was still referenced as a benchmark by developers.[163]

In 1999, a section of Riverside Centre’s 2ha site was sold to Singaporean development company Bloomberg. Bloomberg and its subsidiary, Riverside Developments, engaged Harry Seidler and Associates to design a new mixed-use (residential, retail and commercial) tower for the site, to be called Riparian Plaza.[164] Designed to complement Riverside Centre,[165] and opened in 2005, Riparian Plaza received the AIA’s National Award for Commercial Architecture in 2007.[166]

In 2007, approval was given for the construction of a new high-rise office tower at 111 Eagle Street. The development involved the removal of part of the South Plaza building, containing retail on the ground floor and an opening to Friday’s.[167] ‘One One One Eagle Street’ opened in 2012, receiving national commendations for Commercial Architecture and Sustainable Architecture from the AIA in 2013.[168]

Changes have been made to Riverside Centre to adapt to changing business needs.[169] Such changes have generally been sympathetic to the original design and of a high quality, frequently undertaken with the assistance of Harry Seidler and Associates.[170] Fit-outs in the office tower and plaza buildings have regularly changed to suit new tenants, including remodelling of the ASX floors and the installation of river-facing windows in the formerly windowless lower levels.[171] A coffee shop was added to the foyer in 2007,[172] while the Calder tapestries were replaced by a Robert Owen piece, HAZE (Spectrum Shift), in 2008 and Sydney Ball’s October Fields in 2016 (commissioned by Harry Seidler and Associates, selected by Penelope Seidler and recommended by Greg Holman). Seidler was an admirer of Owen,[173] and Ball’s works had been used in other Seidler towers.[174] The foyer was refurbished in 2016, including new entry doors, café fit-out, reception desk and new furniture and digital tenancy directory installed.[175] The Eagle Street canopy was reglazed, with advice and guidance from Harry Seidler and Associates.[176] The office elevators were remodelled and modernised in 2016-2018, receiving an international award in 2019.[177]

Fit-outs in the plaza eateries were also changed for new occupants in the 21st century, and the Northwest Plaza was converted to a tavern in 2003.[178] Riverfront restaurants, fronting the boardwalk, were opened in 2008 in the space set aside for the riverfront road (The Groove Train in the Northeast Plaza and Jellyfish in the South Plaza).[179] New glass awnings were installed on the plaza buildings in 2006, and a second storey was added to the Northeast Plaza in 2008, both designed by Harry Seidler and Associates’ Greg Holman.[180] The plaza was relandscaped in 2016, receiving an award from the Australia Institute of Landscape Architects Queensland for its ‘respectful’ but not ‘subservient’ response to the ‘iconic building’ in 2018.[181]

The ferry terminal fabric was replaced in 2003,[182] though original fabric was left in the waiting area, including a granite seat and sign, and remains in use in 2023. The marina was reduced at the same time and removed in 2017.[183] The ferry terminal fabric which was replaced is not of State-level cultural heritage significance and is outside the heritage boundary.

The complex was evacuated during the January 2011 floods.[184] The carpark remained closed for a month, and the two boardwalk restaurants were refitted.[185] The boardwalk restaurants were again inundated in February 2022 and refitted.[186]

On 28 July 2023, the place's owner received development approval for the partial demolition of two levels of existing basement car park and full demolition of the existing low-scale buildings located at the northern end of the site to facilitate the reconfiguration of the basement car parking areas and additional bicycle parking and servicing areas and the construction of a 26-storey office building with retail uses provided at the lower levels.[187] The area affected by the development approval is largely outside the heritage boundary.

Description

Riverside Centre (completed 1986) is an office tower complex located at the northeastern edge of Brisbane Central Business District (CBD). It includes an Office Tower, public Plaza, Plaza Buildings, and a section of a riverside promenade known as the Riverwalk. The 1.35ha site fronts Eagle Street to its northwest and the Brisbane River to its southeast, and its other (northeast and southwest) sides are bounded by high-rise commercial and mixed-use buildings. Standing within Brisbane’s Golden Triangle precinct, the complex employs cohesive Modernist design principles and makes a notable contribution to the cityscape.

The complex is laid out with the 40-storey Office Tower standing centrally on the site’s western (Eagle Street) edge, with a low-rise, mixed-use Plaza Building (fronting the Brisbane River to the south of the Office Tower) and a public Plaza that steps down towards the river. The Office Tower’s triangular form maximises views out to the river. The Riverwalk runs along the length of the site’s river edge and extends over the water. Under the Plaza are two levels of underground car parking and service areas.

Riverside Centre contributes to the vista of the Brisbane CBD skyline from the Brisbane River (Town Reach), Kangaroo Point and the Story Bridge (QHR 600240). Its riverfront siting, distinctive forms and surrounding open and low-rise plaza setting accentuate the place within this view.

Features of Riverside Centre of State-level cultural heritage significance include:

  • Office Tower (1986);
  • Plaza (1986), including original landscaping, water feature, curvilinear beam and walkway canopy;
  • South Plaza Building (1986);
  • Riverwalk (section 1986); and
  • Views to and from Riverside Centre and the Brisbane River, Kangaroo Point and the Story Bridge.

Features of Riverside Centre not of State-level cultural heritage significance are:

  • Exterior alterations to the Office Tower’s Brisbane Stock Exchange floors;
  • Office Tower’s basement floor fit-outs and recent building services;
  • Non-original interior office, restaurant, bar and café fit-outs;
  • Non-original Plaza landscape features; and
  • Adjacent recent office tower (111 Eagle Street).

Office Tower

The Office Tower’s triangular plan form with rounded corners is orientated so that one side of the building faces Eagle Street to the northwest, and two sides face northeast and southeast to largely unobscured views up and down the Brisbane River. The 40-storey concrete structure has two basement levels and a tall foyer occupying the entire ground floor at the Plaza level.

The Office Tower’s exterior is a grid of grey granite stone cladding and large banks of fixed windows shielded on the northeast and northwest sides by external metal sunshades. The grid is interrupted by ‘sky terraces’ (recessed open-air balconies) at various locations on the river-fronting (south and northeast) elevations of the building, accessed via some offices. The building has a flat roof, with the top storey externally expressed by having fewer windows and housing the largest ‘sky terrace’, expanding along the eastern corner. The Office Tower exterior has a strong, clear form and a graphic aesthetic quality depicting Modernist principles.

The base of the building (formed by the foyer level and two mezzanine levels above (known as levels 5 and 6; former Brisbane Stock Exchange)) has a solid and heavy exterior appearance. Clad with polished granite stone, this solid form melds at the ground level into two massive hyperboloid columns at either end of the Eagle Street elevation. These columns frame the building’s entrance, which is further emphasised by an undulating, metal-framed glass canopy. The base’s other sides have regularly-spaced columns, between which are enclosures of tall, frameless glass.

The exterior of the building is highly intact, with minor changes including: windows cut into the eastern corner of levels 5 and 6, the removal of the original main entrance doors and replacement in the same location to a larger design, and the removal and replacement of secondary access doors. Tenancy branding, including at the top of the building and at the front entrance, are regularly updated.

The building’s main entrance is from the Plaza from Eagle Street, with secondary entrances from the Plaza on the other sides. The foyer is approximately 15m in height and wraps around the central, triangular, structural service core. Its off-form concrete ceiling features a pattern of exposed radiating and concentric-curved rib beams. The glass foyer walls undulate inwards at the eastern end of the building to accommodate and overlook an exterior water feature in the Plaza. The foyer ceiling lowers on the northeast and south sides of the building, under the former Brisbane Stock Exchange. Between these levels, a cantilevered concrete stair with travertine stone-lined balustrades overlooks the foyer below. The former Brisbane Stock Exchange has been converted to open-plan office tenancies and the originally open mezzanines at the northwest end have been enclosed with glass.

Above the base of the building, repeated concrete floor plates feature open-plan office spaces, supported on a central, triangular, structural service core, with concrete columns at the building’s outer edges. The structural service core contains services such as banks of lifts, fire stairs, services ducts and toilets. The lift heights are staggered, culminating at low, mid and high levels with crossover lift lobbies. Plant rooms are on levels 16, 17, 40 and the rooftop, containing modern equipment. To each level, the central structural service core is surrounded by an approximately 12.5m wide ring of open-plan office space, unimpeded by columns. Tenancy fit-outs (such as partitions, floor surfaces, lighting, furniture, fixtures and fittings) are non-structural and were designed to be changed by respective tenants. No substantial original interior fit-outs to these levels survive. Some alterations to the floor plates have been made to connect and disconnect multi-floor tenancies via stairs, voids and enclosures. 

Panoramic views up and down the river are available from all levels of the triangular Office Tower as a result of its form, the surrounding open space Plaza, and the lowset nature of the Plaza Buildings.

Plaza

The Plaza surrounding the Office Tower provides a pedestrian thoroughfare from Eagle Street at the west end of the site, stepping down to the Riverwalk and Brisbane River at the east. The Plaza is an open, largely uncovered space, providing for a public thoroughfare across the site, and for access into the Office Tower and three Plaza Buildings. The open space of the Plaza allows for views of the Office Tower from the ground plane, and for the Office Tower to access light and air. While new landscaping has been added, some original plants and planter beds have been retained and / or remain in early locations.

At its east end, the Plaza features a curved walkway canopy supported by round columns. A water feature extends into the east corner of the Office Tower, and cascades down to a pond at the Riverwalk level, following the steps of the adjacent curved stairs and stair / ramp (referred to as a stramp). It has a row of fountains in the upper pond (adjacent to the Office Tower) and is crossed by the Plaza flooring at this level (the crossing has been widened). Views of the river, framed by a raised curvilinear beam, become apparent at this side of the Plaza.

Features of the Plaza of State-level cultural heritage significance include:

  • Open, largely unroofed, publicly accessible space use;
  • Thoroughfare connection between Eagle Street and the Brisbane River and Riverwalk;
  • Natural split ‘porfido’ (grey porphyry) stone floor finish, generally smaller in profile to stairs and ramps, with expressed expansion joints extending in line with the Office Tower foyer’s radiating travertine strips  
  • Water feature, including: row of fountains and upper pond extending into the eastern corner of the Office Tower, stepped cascading section, and lower pool at the Riverwalk level; dark grey tiles (with lines of light grey tiles extending consistently with the Office Tower foyer’s radiating travertine strips) to the floor and side walls; metal edging; polished grey granite edge caps; and walkway intersection (excluding widening);
  • Curved walkway canopy, extending from the northeast side of the Office Tower, including its: wide, circular, concrete columns; largely flat roof; flat sheet-lined ceiling; downlight locations; and wide, rendered parapet;
  • Curvilinear box beam, extending north from the South Plaza Building, including its: narrow, curved form with deep profile; rendered finish; locations of recessed downlights (lights replaced); and open space above and below framing views of the river;
  • Curved stairs and remnant curved stairs, including: at the northeast end of the site, from the Plaza upper level down to the Riverwalk; south and southeast of the Office Tower, adjacent to the South Plaza Building; and northeast of the Office Tower;
  • Early landscaping / planter beds, including:
    • Palm trees (Livistona spp.) north of the water feature,
    • Planter bed south of the water feature’s upper pond (fig tree replaced),
    • Circular planter bed to ground level of South Plaza Building containing palm trees (including circular opening through to level above), and
    • Locations of trees to southwest and north of Office Tower;
  • Original stairs leading to the basement, including rendered walls with polished grey granite capping, and glass balustrades with metal handrails of a circular profile;
  • Circular metal drain grates, debossed with Riverside Centre logo graphic; and
  • View of the Brisbane River from the Plaza, framed by the curvilinear beam and water feature.

Features of the Plaza not of State-level cultural heritage significance include:

  • Non-original planter beds and seats (identifiable as concrete plinths with rounded edges and panelled timber seats) (added 2016)
  • Non-original landscaping;
  • Non-original tubular metal stair handrails (added 2016);
  • LED light fitting replacements;
  • Metal light poles;
  • Non-original way-finding and ‘Riverside Centre’ signs; and
  • Walkway widening through water feature (upper level).

South Plaza Building

The low-rise South Plaza Building stands within the Plaza at the southeast end of the site.  It features curved wall forms and a flat roof. Views of the river are obtained from its balconies / terraces and large window openings. 

The three storey building features a food court on the central/ground floor (aligned with and accessed via the upper plaza level), and a restaurant / bar on the first floor. Its length has been reduced, with the western portion of the building removed to accommodate 111 Eagle Street (c2007-09). An external northeastern stair and an internal north-western stair provide access between the ground and first floors. Each level features unroofed balconies / terraces and large glass openings to the east and southeast sides, overlooking the Plaza, river and Story Bridge. A semi-circular plant room extends above the first floor. 

Large circular planter beds on the northwest side of the building have low concrete walls with polished grey granite caps. A circular floor opening with concrete walls to the upper level is vertically aligned with the ground floor planter bed, providing light and growth-space to the plants below.

The lower (Riverwalk) level’s former void space enclosure for a proposed river road has been opened for a restaurant fit-out (not of State-level cultural heritage significance).

Features of the South Plaza Building of State-level cultural heritage significance are:

  • Original building form and footprint (including organic and curved elevations);
  • Low-level building form, with flat roof, and semi-circular parapets / plant room;

[8] Between 1950 and 1965 few office highrise buildings were constructed in Brisbane. These included: Mutual Life & Citizens (MLC) Insurance Building, the first curtain-wall high-rise building in Queensland (Bates Smart and McCutcheon, in association with Conrad and Gargett, 1956); Friendly Society Building (1957), and; Taxation Building (1961) These all stood below the 132ft height limit.

The shift of the wharves occurred in port cities worldwide in the second half of the twentieth century, as small inner-city wharves could no longer accommodate larger ships or containerisation facilities. In Brisbane, additionally, the Kangaroo Point bend was too difficult for large ships to handle. Port facilities were relocated downstream from the 1940s, and ultimately the Port of Brisbane was built near the mouth of the river.

Sydney and Melbourne had also experienced high-rise office growth, but, according to a 1985 commentator, ‘The boom in Sydney had to stop earlier because they simply ran out of space, and in Melbourne the boom just wasn’t as strong. Brisbane was really it – the boom was extraordinarily strong and it went without any hitches’: Frank Gelber, BIS Shrapnel, quoted in Courier Mail, 22 November 1985, p.28.

[30] This development received comment in the Expo 88 Queensland Pavilion Souvenir Book: ‘Since the ’82 Games high rise development has stretched up along the banks of the river, great canyons of steel, concrete and glass. Modern buildings that reflect the gold of the early morning sun.’ (Cited in Ross Fitzgerald, Lyndon Megarrity and David Symonds, Made in Queensland: A new history, St Lucia: University of Queensland Press, 2009, p.186).
[31] No objective rating system of building classifications existed at the time. The Building Owners and Managers Association and Property Council of Australia’s Office Quality Grade Matrix was developed in the early 1980s to aggregate vacancy statistics rather than as a building ratings tool, though it was used as such (and in 2003, Riverside Centre and Waterfront Place were ranked as Brisbane’s only premium buildings: Bob Wilson, ‘Curtain back at desk after an interrupted tour of duty’, Courier Mail, 14 February 2003, p.39). Guidelines for office building quality were not developed until 2006. In the interim, the real estate market used subjective terms of prime, premium, A-grade etc. Jeff Sommerfield, ‘Making the grade’, Courier Mail, 25 June 2004, pp.29&37; Stephen Conroy, ‘Classification of buildings loosely used,’ Courier Mail, 25 June 2004, p.39; Property Council of Australia, ‘A Guide to Office Building Quality: Third edition’, https://www.propertycouncil.com.au/media-releases/a-guide-to-office-building-quality-third-edition, accessed July 2023.
[32] See, e.g., ‘Industrial tenants join CBD trend to upgrade,’ Courier Mail, 20 September 1985, p.28 for reference to ‘landmark buildings such as 12 Creek Street [Blue Tower], the Riverside Centre, the Colonial Mutual building and Santos House [Capital Centre]… taking tenants from what is now regarded as second-level accommodation’. A Jones Lang Wootton (JLW) survey in October 1985 identified Santos House, Comalco Place [Blue Tower], and the Colonial Mutual building as ‘prime’, with the forthcoming Riverside Centre and Central Plaza One also to fit into that category: Lisa McKee, ‘Prime office space “short”, Courier Mail, 25 October 1985, p.27. JLW again identified Colonial Mutual, Comalco Place, Santos House and Riverside Centre as ‘prime’ office buildings in January 1987, when JLW’s associate national director said that ‘contrary to popular belief, there is not an abundance of prime new office space available’: ‘Brisbane CBD sales rocket’, Courier Mail, 23 January 1987, p.20.

Brisbane had not been surveyed in the 1979 commercial property report, but its rents were on par with the second-lowest tier of cities which had been included in the report, with only one city (Johannesburg) commanding lower commercial rents. In the same decade Sydney experienced relatively little change, dropping from the fifth most expensive city in the world for commercial rents in 1979, to seventh most expensive city in 1988, and climbing to the sixth most expensive city in 1989.

After 1990, high-rise office buildings were constructed at 310 Ann Street (circa 1992), State Government offices on George Street (1993), and the Harry Gibbs Commonwealth Law Courts (1994). The Crow Howarth building, opened in 2001 at 120 Edward Street, was announced as the ‘first commercial office building in the Brisbane CBD for over a decade’: Graham de Gruchy, Architecture and Urban design in Brisbane, Vol. 2, Brisbane: Boolarong Publications with Kookaburra Books, 2012, p.40. One project – Admiralty Wharves – was ultimately constructed in the 20th century, but without office towers as originally planned.

[40] Forecasts for further growth included the state’s growing population, the ongoing mining boom and resources development, and potential for growth in leisure and tourism industries, all of which would be reflected in demand for commercial office space in the central business district.

[41] The riverside road had been recommended in the 1965 Brisbane Transport Study, undertaken by American planning firm Wilbur Smith and Associates, and adopted by the Brisbane City Council as policy. The road, or Petrie Bight Expressway, was to be a twin to the Riverside Expressway running along North Quay to the Captain Cook Bridge, and any riverfront development would have to make provision for the road. The proposed expressway was partly responsible for the inability of British developers Hammerson Group to complete its proposed three-tower riverfront plaza, restaurant and bridge development. Later it contributed to the collapse of a plan to open the Hilton Hotel on a riverfront site. The Hilton instead opened in Queen Street, in a building designed by Harry Seidler and Associates. ‘$5m road is part of the deal’, Courier Mail,  27 August 1982, p.15; ‘Lend Lease hopes to drop Riverside Centre road level’, Courier Mail, 8 June 1984, p.32; 'Council positive on $90m Mall hotel', Courier Mail, 24 February 1984, p.9'  James R Stewart, ‘Bringing back the river’, Courier Mail, 12 April 1985, p.12; Lisa McKee, ‘Lend Lease set to go shopping for Qld centres’, Courier Mail, 3 February 1986, p.24; Lisa McKee, 'Hotels price ware in reverse', Courier Mail, 2 May 1986, p.24; David Fagan, ‘From rundown wharves to blue chip property’, Courier Mail, 17 October 1986, p.26; Helen Gregory, The Brisbane River Story: Meanders through time, Brisbane: Australian Marine Conservation Society, 1996, p.177

The accumulation of multiple large sites for a single development was not new to Lend Lease: its Brisbane project followed the successful pattern established in the 1960s with Sydney’s Australia Square. In Brisbane, this involved purchases from a large number of reluctant sellers, who, according to the Lend Lease Corporation managing director, had to be made ‘offers they couldn’t refuse’ (Courier Mail, 10 February 1984, p.11). For Lend Lease, the high cost was offset by adherence to its risk avoidance philosophy, As Lend Lease Development’s Queensland manager, Trevor Reddacliff, stated: “As a company, Lend Lease does not speculate and it does not create demand. A lot of leaders fail. We as a company would prefer to follow an established demand and probably pay a premium to avoid risk.” David Fagan, ‘Riverside’s opening fanfare hides high-tech view of future’, Courier Mail, 3 October 1986, p.24.

[61]  While a small number of sources refer to the office tower as a 38-storey or 42-storey building, most sources refer to the office tower as having 40 storeys (including Kenneth Frampton, the Royal Australian Institute of Architects (Queensland Chapter), Harry Seidler and Associates, and Lend Lease). GPT has referred to the building as 40 storey (with 36 tenantable: General Property Trust Investment, Riverside report: A Towering Success, Brisbane: General Property Trust Investment, 1986), 41 storey (https://gpt.com.au/property/riverside-centre), and 42 storey (with 37 tenantable: https://www.riversidecentre.com.au/about-building/building-profile). The inconsistencies appear to be due to the inclusion or exclusion of the two basement levels, the number of office levels (possibly including or excluding the open-air penthouse sky terrace), and the number of storeys occupied by the foyer. The tower’s height has also been inconsistently recorded as between 146m and 154.7m.

[63] In 1989, Riverside Centre’s entrance canopy was described as ‘a glass rendition of the traditional verandah’ in a piece by Harry Seidler, who stated, ‘The fact that we occasionally have downpours can generate a response in design solutions for the covering of building entrances.

[78] Seidler considered it ‘socially irresponsible to build to high indexes of 12 or 14 unless there is a limit on site cover of no more than 25% to 35%... to generate some breathing space of the additional thousands of people that work in such buildings to create genuinely useful, new, open or sheltered urban spaces – places of repose and recreation – much needed open public space on private land.’ Harry Seidler, ‘A Perspective on Architectural Directions’, in LS Beedle (ed), Second Century of the Skyscraper, Boston: Springer, 1988, pp.165-181, at p.169.

According to Kenneth Frampton, ‘Seidler devoted much attention to the systematic manner in which the work would be erected and to the precise detailing of its tectonic form. Thus we find him writing of the triangular plan of the office tower: “A triangular office configuration with one third of a circle in each corner results in a building with only one span length for every beam and only one façade unit of identical structural spacing. This allows a rapid repetitive construction cycle…”: Kenneth Frampton, Riverside Centre, Harry Seidler, Cammeray, NSW: Horwitz Grahame Pty Ltd, 1988, p.4.
[86] Lend Lease had successfully negotiated a reduction in the height level of the riverside road as plans for the development were underway (Courier Mail, 8 June 1984, p.32, 22 June 1984, p.27). The riverside road was publicly criticised, particularly as the river itself was increasingly seen as an asset (e.g., Courier Mail, 17 August 1984, p.28, 12 April 1985, p.12); and the road was finally scrapped early in Lord Mayor Sallyanne Atkinson’s administration (Courier Mail, 10 May 1985, p.26).

[105] The office tower’s ‘intelligence’ was centred on a Local Area Network, controlling services and building automation, communicating automatically with carpark and services, lights, and voice-activated air conditioning.

This was to be GPT’s first investment in Queensland, and Lend Lease chairman GJ Dusseldorp faced questions from GPT unitholders over why they should invest in a property in Brisbane. The state’s population growth and the city’s favourable development policies were credited with giving Brisbane the ‘best potential for growth of all the capital cities’: Courier Mail, 27 January 1984, p.13, 8 February 1984, pp.11 & 28, and 10 February 1984, p.11; Sydney Morning Herald, 8 February 1984, p.27.

[108] The foyer was divisive: the 1988 Robin Dods award jury president expressed reservations over its height (Lisa McKee, ‘Further accolades for Riverside, Arts Centre’, Courier Mail, 6 June 1988, p.36; and Royal Australian Institute of Architects, Queensland Chapter, Chapter News, June 1988, p.9), but in 1992 the RAIA Queensland Chapter president called the foyer ‘outstanding’ in its uniform use of materials and skilful integration of the structural elements into the decoration: James Woods, ‘Foyers: providing a sense of arrival’, Courier Mail, 30 March 1990, p.17.
[109] Royal Australian Institute of Architects, Queensland Chapter, Chapter News, August 1987, p.2. The curvilinear beam was questioned by architectural commentators and members of the public (as it ‘seems to interfere with the river relationship and restricts views to Kangaroo Point’, but, Seidler explained, it ‘served a most important aesthetic purpose. It defines and forms the visual boundary to the public plaza (without which the space would just “fall out” towards the river). This is an essential factor in creating a valid urban space in which people feel “contained” and are tempted to linger, which they do not in open plazas without visual boundaries’: ‘Jury Comment’ and Harry Seidler, ‘Best Building’, in Royal Australian Institute of Architects, Queensland Chapter, Chapter News, August 1987, p.6; ‘Letters to the editor’, Courier Mail, 2 October 1986, p.2

FA Pidgeon, then developing the Waterfront Place development nearby, said that Riverside Centre ‘set the benchmark and created an awareness of the desirability of prestige space,’ and that Riverside ‘had demonstrated that when a building stood out “a country mile” ahead of the others, it created its own demand’, adding that Waterfront Place ‘will set new standards’ (‘Waterfront Place seen as landmark’, Courier Mail, 5 June 1987, p.29). In 1989 the chairman of the Queensland-based development company Kern, Barry Paul, said that Brisbane needed to create more modern buildings to remain competitive: ‘“If Brisbane doesn’t produce more Riversides and more Waterfronts, then the Brisbane CBD will be obsolete.”’ (‘Power needs make 60s, 70s, buildings obsolete’, Courier Mail, 27 October 1989, p.24).

Lend Lease had amassed a 2 hectare site in total (both freehold and leasehold), but stage one had been laid out on 1.4 hectares. Few other office high-rise towers were erected on such large sites, with only two subsequent projects (Waterfront Place, 1990, and Cathedral Square, 1989) on par. The Riverside Centre site also dwarfed several CBD sites intended solely for public purposes or recreation, including Post Office Square, King George Square, Anzac Square, and Queens Gardens. Certificates of Title; Queensland Globe; 'Waterfront Place seen as landmark', Courier Mail, 5 June 1987, p.29.
[141] The official cost of the project was not publicly released, though several different figures were reported. Initially reported as a $100 million in 1981, the estimate had climbed to $200 million by August 1982. By December 1983 it was reported as a $250 million project, more expensive than both Expo ($180 million) and the Gold Coast casino ($175 million), as Lend Lease revealed that it had already spent $40 million on the development. By 1984 this cost had been revised again to $300 million, but that figure was to include a second stage development. The development was sold to General Property Trust in 1986 for a sign-over price of $171.5 million and a total sales price of about $200 million. The project was mostly commonly referred to as a $200 million project, including by contractors Civil and Civic (Terry Ryder, ‘$250m to remodel the river skyline’, Courier Mail, 9 December 1983, p.1; Terry Ryder, ‘Lend Lease pays $40m to plan Riverside’, Courier Mail, 9 December 1983, p.17; Malcolm Wilson, ‘The jewel in the Lend Lease crown’, Sydney Morning Herald, 8 February 1984, p.27; Terry Ryder, ‘Lend Lease “re-thinks” $300m Centre design’, Courier Mail, 28 September 1984, p.28; ‘Top Job, Team!’, Courier Mail, 11 October 1985, p.13; Financial Review, 18 October 1985, p.18; Lisa McKee, ‘Lend Lease set to go shopping for Qld centres’, Courier Mail, 3 February 1986, p.24; ‘Riverside planned to finest detail’, Courier Mail, 30 May 1986, p.29).
[142] Of the three projects, only Riverside Centre was recognised nationally for its architectural achievement, and only Riverside Centre has a surviving open public plaza. Central Plaza (corner of Creek, Eagle and Queen streets) received the Royal Australian Institute of Architects Queensland Chapter award in 1989, BOMA award in 1989, and another RAIA (Queensland Chapter) award for its foyer in 1990. It was within the ‘Golden Triangle’ precinct but did not have a riverfront site, and did not include a public open plaza.

Waterfront Place (1990) provided public space in its waterfront Eagle Street Pier retail, restaurant and recreation development, which opened to the public in 1989. Initially planned as a comprehensive riverfront site, went through several developers and site negotiations before its recreational, retail and restaurant feature, Eagle Street Pier opened slightly further downstream than its office tower. Situated just south of the Golden Triangle, it connected to the precinct via a footbridge and a riverfront walkway. The development won the Commercial Award of the RAIA Queensland Chapter in 1990, though did not receive national recognition. (Royal Australian Institute of Architects Queensland Chapter, Awards 1990.) Noted Australian architect and academic Dr Paula Whitman noted the difference between Eagle Street Pier and Riverside Centre in 2001: “Eagle Street Pier is very cut off from the street behind. Riverside works better because you go past and see what is beyond. It invites you in to the fabulous connection to the river. It’s doing all the right things. But with the pier you get a wall.” (‘The eagle has landed’, Courier Mail, 26 May 2001, p.M.04). The Eagle Street Pier was demolished in 2023 (site visit, May 2023).
