The curtainwall encloses a secondary stairwell, and is separated from the gallery spaces by an internal wall. “Putting this diagrid element on an angle gives it visual energy,” says Mitchell. “The glazing also allows people using the stairs inside to appreciate the magnificent bush and harbour views, and the people travelling through this circulation area help to animate the exterior.” Similarly, the long slot windows in the building, which bring light into the main spiral staircase and landings, are enlivened by the foot traffic inside.

These bright, open spaces contrast the darker, more compressed nature of the galleries.
