Sydney Opera House
The cost of the project so far, even in October 1966, was still only $22.9 million, less than a quarter of the final $102 million cost. However, the projected costs for the design were at this stage much more significant.
Postmodern architecture
The Sydney Opera House in Sydney, Australia, by the Danish architect Jørn Utzon (1918–2008) is one of the most recognizable of all works of postwar architecture, and spans the transition from modernism to postmodernism. Construction began in 1957 but it was not completed until 1973 due to difficult engineering problems and growing costs. The giant shells of concrete soar over the platforms which form the roof of the hall itself. The architect resigned before the structure was completed, and the interior was designed largely after he left the project. The influence of the Sydney Opera House, can be seen in later concert halls with soaring roofs made of undulating stainless steel.
