The Residential Tower at Aurora Place reflects the historical and architectural quality of the existing buildings in this unique location of Macquarie Street at the same time promoting a different concept of sociability between the elements of the buildings and with respect to the surrounding natural environment. As part of a truly urban sculpture, the building responds to the context of the site, the nature of the views, winds and orientation whilst also aiming to produce a memorable living environment. Macquarie Street and the surrounding cityscape generally tends to be about an alignment of buildings along the street edge. Several of the more historic and significant buildings in Macquarie Street are also finished with earthy materials such as sandstone or terracotta. In a reflection of this context, the design incorporates a ground plane based on an orthogonal geometry of terracotta-clad buildings which fit into the existing city grid. From this base the building grows into a more flamboyant glass shell. The earthy terracotta, which wraps the solid rectilinear elements, contrasts in texture, colour and precision with the curvilinear smooth white mildly reflective glass facades. Pure ultra-white glass is used in a number of different ways as the interface between the interior and the exterior, the ground and the sky.
