From 1957 to 1963 the design team went through at least 12 iterations of the form of the shells trying to find an economically acceptable form including schemes with parabolas circular ribs and ellipsoids before a workable solution was completed.

The sydney opera house is primarily made from concrete granite glass and ceramic materials. Approximately one million tiles were placed on the roof surfaces in the form of repetitive precast panels. Its trademark white shells are made from precast concrete reinforced with steel and are covered by over 1 million ceramic tiles.
