The facility features a modern expressionist design, with a series of large precast concrete "shells", each composed of sections of a sphere of 75.2 metres (246 ft 8.6 in) radius, forming the roofs of the structure, set on a monumental podium. The building covers 1.8 hectares (4.4 acres) of land and is 183 m (600 ft) long and 120 m (394 ft) wide at its widest point. It is supported on 588 concrete piers sunk as much as 25 m (82 ft) below sea level.
Although the roof structures are commonly referred to as "shells" (as in this article), they are precast concrete panels supported by precast concrete ribs, not shells in a strictly structural sense. Though the shells appear uniformly white from a distance, they actually feature a subtle chevron pattern composed of 1,056,006 tiles in two colours: glossy white as well as matte cream. The tiles were manufactured by the Swedish company, Höganäs AB, which generally produced stoneware tiles for the paper-mill industry.
Apart from the tile of the shells and the glass curtain walls of the foyer spaces, the building's exterior is largely clad with aggregate panels composed of pink granite quarried at Tarana. Significant interior surface treatments also include off-form concrete, Australian white birch plywood supplied from Wauchope in northern New South Wales, and brush box glulam.
Of the two larger spaces, the Concert Hall is in the western group of shells, the Joan Sutherland Theatre in the eastern group. The scale of the shells was chosen to reflect the internal height requirements, with low entrance spaces, rising over the seating areas up to the high stage towers. The smaller venues (the Drama Theatre, the Playhouse, and The Studio) are within the podium, beneath the Concert Hall. A smaller group of shells set to the western side of the Monumental Steps houses the Bennelong Restaurant. The podium is surrounded by substantial open public spaces, and the large stone-paved forecourt area with the adjacent monumental steps is regularly used as a performance space.
Performance venues and facilitiesEdit
It houses the following performance venues:
- The Concert Hall, with 2,679 seats, the home of the Sydney Symphony Orchestra and used by a large number of other concert presenters. It contains the Sydney Opera House Grand Organ, the largest mechanical tracker action organ in the world, with over 10,000 pipes.
- The Joan Sutherland Theatre, a proscenium theatre with 1,507 seats, the Sydney home of Opera Australia and The Australian Ballet. Until 16 October 2012 it was known as the Opera Theatre.
- The Drama Theatre, a proscenium theatre with 544 seats, used by the Sydney Theatre Company and other dance and theatrical presenters.
- The Playhouse, an end-stage theatre with 398 seats.
- The Studio, a flexible space with a maximum capacity of 400, depending on configuration.
- The Utzon Room, a small multi-purpose venue, seating up to 210.
- The Forecourt, a flexible open-air venue with a wide range of configuration options, including the possibility of utilising the Monumental Steps as audience seating, used for a range of community events and major outdoor performances. The Forecourt will be closed to visitors and performances in 2011–2014 to construct a new entrance tunnel to a rebuilt loading dock for the Joan Sutherland Theatre.
Other areas (for example the northern and western foyers) are also used for performances on an occasional basis. Venues are also used for conferences, ceremonies and social functions.
