This 20,000 seat professional basketball stadium and community sports centre is perched on a grassy outcrop, its veil of green painted steel ‘leaves’ hanging five metres beyond the world-class basketball arena inside. This creates an exterior service zone (like the branches of a tree) for the building’s gloriously accessible array of air-handling equipment.

In total contrast, the sports centre is a cave carved from the ferrous rock. Low-level pool lighting and dark materials give this ‘local public amenity’ space an aura of five star hotel glamour and tranquility.
