Former president of the New Zealand Institute of Architects. Known for such buildings as Telecom Towers, Civic Square and Wellington Library, and Jade Stadium.
He used corrugated iron, plaster, stainless steel, and fibre glass on his earliest projects. He considered his era's architecture to be boring and began incorporating a vernacular style inspired by colonial buildings into his structures. He worked on the design of the Bangkok rapid transport system.
He was appointed Architectural Ambassador to Christchurch in 2010 and 2011 after the Canterbury earthquakes.
His first major project was a home and studio for his family called Athfield House; he married in 1962.
He and actor Russell Crowe were both born in New Zealand.
