Riparian Plaza is a 53-storey skyscraper, accommodating both commercial offices and residential apartments.
The building stands at 250 m (820 ft) in height to its communications spire and 200 m (660 ft) to its roof.
It was Brisbane’s tallest building until it was surpassed by Aurora in 2006 and is a particularly iconic building on the Brisbane skyline.
It is a mixed use building, with 11 car park levels from the ground up, 25 column-free commercial levels, and 12 residential levels originally housing 50 penthouse apartments.
It sits adjacent to Riverside Centre on the waterfront of the Brisbane River.
Riparian Plaza is higher and larger in scale as its promenade continues along the river.
The shape of the tower has been carefully formed to maximise the outlook for occupants up and down the river.
The building offers facilities for the public, such as restaurants and plazas.
Riparian Plaza was designed by architect Harry Seidler, who also designed the adjoining Riverside Centre.
Robert Bird Group were the structural engineers for the project.
Most office spaces have river views, due to the 45-degree angle to the river of the building and the lack of columns on these mid-level floors.
Each penthouse has its own curvilinear, projecting terrace that faces the river.
The cantilevering balconies have a highly sculptured shape.
Architect Harry Seidler claimed the composite stacking of sectors vertically is unique in Australia.
In October 2007, Riparian Plaza won the top prize for commercial architecture at the annual national architecture awards.
