Aurora Place is the common name of Renzo Piano's award winning office tower and residential block on Sydney's Macquarie Street. Its official name is the ABN AMRO building, after its principal tennant. The 41 storey structure is 218 m high to the top of the spire and 188 m to the roof.

The building has an unusual geometric shape where not one panel was parallel to any grid. The east façade bulges out slightly from its base, reaching its maximum width at the top floors. The curved and twisted shape of east façade is aimed to correspond spatially with Sydney Opera House and to represent the sublime marine environment of the harbour. The exterior glass curtain-wall extends beyond the main frame, creating an illusion of its independence. The steel spire attached to north facade is 75m in length.

[edit] History

The building was built on the site of the former NSW Government Office Block by Bovis Lend Lease. The assumptions of a planned tower were first presented to the Central Sydney Planning Committee in 1996, when three main architects: Mark Carroll, Shunji Ishida and Renzo Piano put forward the innovative project. The building was sold in January 2001 for $485 million. Aurora Place was the winner of prestigious 2002 Property Council of Australia Rider Hunt Award, handled out for technical and financial qualities.

[edit] Construction Materials

Materials that are used for this building were unique compared to its neighbours, Chifley Tower [Kohn, Pederson Fox architects, 1988] and Governor Phillip Tower [Denton, Corker Marshall architects, 1994]. The facade which makes up the primary component of the building is the milky white fritted glass which has been laminated. The aesthetics of the material gives a visual metaphor of a sail. It is inspired by the tiling of the Sydney Opera House, which is less than half a mile North of the building. Terracotta tiles makes up much of the lower section of the building to contrast the white dominated glass cladding. It also reconciles the orange cladded lobby and the residential complex.
