Sydney Opera House, Australia - Odd-Shaped Buildings on Waymarking.com

From wikipedia: The Sydney Opera House is an expressionist modern design, with a series of large precast concrete 'shells', each taken from a hemisphere of the same radius, forming the roofs of the structure.

The 'shells' are covered with over a million glossy white and matte cream tiles, though from a distance the tiles look white. Despite their self-cleaning nature, they are still subject to periodic maintenance and replacement.

Planning for the Sydney Opera House began in the late 1940s when Eugene Goossens, the Director of the NSW State Conservatorium of Music, lobbied for a suitable venue for large theatrical productions. By 1954, Goossens succeeded in gaining the support of NSW Premier Joseph Cahill, who called for designs for a dedicated opera house.

The competition was launched by Cahill on 13 September 1955 and received a total of 233 entries from 32 countries. The basic design announced in 1957 was the one submitted by Jørn Utzon, a Danish architect.

The engineers were initially unable to find an economical and structurally viable solution to construct the 'shells'. From 1957 to 1963 the design team went through at least twelve iterations of the form of the shells before a workable solution was completed. The design work on the shells involved one of the earliest uses of computers in structural analysis in order to understand the complex forces the shells would be subject to.

The Opera House was formally completed in 1973, having cost $102 million. The original cost estimate in 1957 was £3,500,000 ($7 million). The original completion date set by the government was January 26, 1963.
