The Sydney Opera Housedesigned by 2003 Pritzker Prize winner and Danish architect Jørn Utzon is situatedon Bennelong Point in Sydney Harbour, close to the Sydney Harbour Bridge. It isa multi-venue performing arts center and opened on 20 October 1973 with thecost of 1.2 million Australian Dollars. The building covers 1.8 hectares ofland and is 183 m long and 120 m wide at its widest point. Identified as one ofthe 20th century’s most distinctive buildings and one of the most famousperforming arts centres in the world, the Sydney Opera House became a UNESCOWorld Heritage Site on 28 June 2007. The designer is inspired bythe orange with half skin. While the built facility features a modernexpressionist design, with a series of large precast concrete"shells", each composed of sections of a sphere of 75.2 metresradius, forming the roofs of the structure, set on a monumental podium. Thedistinctive roof comprises sets of interlocking vaulted ‘shells’ set upon avast terraced platform and surrounded by terrace areas that function aspedestrian concourses. The two main halls are arranged side by side, with theirlong axes, slightly inclined from each other, generally running north-south.The auditoria face south, away from the harbour with the stages located betweenthe audience and the city. The Forecourt is a vast open space from which peopleascend the stairs to the podium. The Monumental Steps, which lead up from theForecourt to the two main performance venues, are a great ceremonial stairwaynearly 100 metres wide. Each shell is composed of pre-cast rib segments radiatingfrom a concrete pedestal and rising to a ridge beam. The shells are faced inglazed off-white tiles while the podium is clad in earth-toned, reconstitutedgranite panels. The glass walls are a special feature of the building,constructed according to the modified design by Utzon’s successor architect,Peter Hall. Apart from the tile of the shells and the glass curtain walls ofthe foyer spaces, the building’s exterior is largely clad with aggregate panelscomposed of pink granite quarried at Tarana. Significant interior surfacetreatments also include off-form concrete, Australian white birch plywoodsupplied from Wauchope in northern New South Wales, and brush box glulam.
