Sydney Opera House

Brief Information

The Sydney Opera House stands on Bennelong Point, where before it came Bennelong's house, a fort, and a tram depot. This matters not as a long prehistory, but as a change of scale: the place once served defense and transport, and became a building that is read from the harbor above all by the shape of its roof.

Its recognizability rests on a series of sail-like shells. The design was associated with the yachts in Sydney Harbour, but realizing this idea proved more difficult than expected: instead of three years, construction took about ten, and the cost rose from roughly seven to about one hundred million Australian dollars. After that, the roof stops being merely a striking silhouette: it is the visible result of an engineering search.

What to Notice First

It makes sense to compare the building's position with its roof. The theatre is surrounded by water on three sides and looks like part of the peninsula; a single artificial platform divides it into an open exterior part and an interior part hidden under the water, where performances are prepared. In this way, the place works at once as the city's stage and as a complex production machine.

The roof is assembled not from arbitrary “sails,” but from shells of a single concrete sphere. Triangular precast panels rest on ribs, so the different vaults retain a related form. The surface is covered with more than a million azulejo tiles in two shades: glazed white and matte cream. From a distance the roof appears white, but the material is designed for changing light. The pink granite outside adds a second layer: the heavy base and the visually light roof work through contrast.
