Conceptual sketches were enough for Jorn Utzon to win the design competition in 1957 to build on Sydney's best site - previously occupied by a tram depot! By 1958 the tramsheds were gone and construction began in 1959 - before the design was complete. By the start of 1961 work was running almost a year behind schedule. After long and storied construction process it was finally opened in 1973. Our Sydney Opera House has won architecture awards in the 1970s, 1980s, 1990s, 2000s, and 2020s.
