Office building with a 15-storey atrium at a new development site in Paddington Basin

The building is designed around the idea of three triangles, which allows volumes and planes to fold into and wrap around each other. The elevation changes around the exterior of the building, so that each facade addresses a particular situation.

The north elevation presents a solid, rusty red curtain while on the opposite side is a wall of fritted colour. Turning the corner, the elevation turns in to a wall of protruding and receding volumes, then changes again into a sleek curtain wall of chequer board pattern.

A red prism of carmine, bisects the building, dividing up its 15-storey mass as well as defining its silhouette.
