A centre for the Salvation Army with a grand public space nestled into the heart of Te Aro, the Citadel is still performing sterling service nearly 30 years after its construction. The form is simple, with rusticated post-modern bands of coloured stone wrapping around the half-drum, and a splendidly tactile series of inverted timber roof trusses standing on end, hoisting the cupola aloft. This project still sings loud.
