Whatever else he did in his long career – as usual, the Wikipedia has more – it’s almost impossible to imagine Sydney without that building. Indeed, it’s almost impossible to imagine an Australia without it. It’s driven Melburnians mad for decades trying to find a similarly iconic building (a quest that has been thankfully abandoned).

Hopefully, the process of renovating the Opera House, which was proceeding with the cooperation of Utzon and his son, will result in a building whose interior – and acoustics – match its astonishing exterior. As a further memorial, perhaps state governments (and this seems to apply particularly to the NSW state government) can find a way to encourage better architecture, not just for icon buildings but across the board. Utzon, whose career also included work on low-cost housing in Denmark, would surely approve.
