Opera House

Sydney Opera House, Australia

The Sydney Opera House is a multi-venue performing arts centre in Sydney, New South Wales, Australia. It was conceived and largely built byDanish architect Jørn Utzon, opening in 1973 after a long gestation that had begun with his competition-winning design in 1957.Utzon received the Pritzker Prize, architecture's highest honour, in 2003. The Pritzker Prize citation stated:There is no doubt that the Sydney Opera House is his masterpiece. It is one of the great iconic buildings of the 20th century, an image of great beauty that has become known throughout the world – a symbol for not only a city, but a whole country and continent.The Sydney Opera House was made a UNESCO World Heritage Site on 28 June 2007. It is one of the 20th century's most distinctive buildings and one of the most famous performing arts centres in the world.The Sydney Opera House is on Bennelong Point in Sydney Harbour, close to the Sydney Harbour Bridge. It sits at the northeastern tip of theSydney central business district (the CBD), surrounded on three sides by the harbour (Sydney Cove and Farm Cove) and inland by the Royal Botanic Gardens.

Contrary to its name, the building houses multiple performance venues. The Sydney Opera House is among the busiest performing arts centres in the world, hosting over 1,500 performances each year attended by some 1.2 million people. It provides a venue for many performing-arts companies, including the four key resident companies Opera Australia, The Australian Ballet, the Sydney Theatre Company and the Sydney Symphony Orchestra, and presents a wide range of productions on its own account. It is also one of the most popular visitor attractions in Australia, with more than seven million people visiting the site each year, 300,000 of whom take a guided tour. 

The Sydney Opera House is a modern expressionist design, with a series of large precast concrete "shells", each composed of sections of asphere 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 of the Sydney Opera House are commonly referred to as "shells" (as they are in this article), they are in fact not shells in a strictly structural sense, but are instead precast concrete panels supported by precast concrete ribs.]The shells are covered in a subtle chevron pattern with 1,056,006 glossy white- and matte-cream-coloured Swedish-made tiles from Höganäs AB, a factory that generally produced stoneware tiles for the paper-mill industry.  though, from a distance, the shells appear a uniform white.

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 plywoodsupplied from Wauchope in northern New South Wales, and brush box glulam. 

Of the two larger spaces, the Concert Hall is located within the western group of shells, and the Opera Theatre within 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 and up to the high stage towers. The smaller venues (the Drama Theatre, the Playhouse, and The Studio) are located 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, of which the large stone-paved forecourt area with the adjacent monumental steps is also regularly used as a performance space.

Stage III, the interiors, started with Utzon moving his entire office to Sydney in February 1963. However, there was a change of government in 1965, and the new Robert Askin government declared the project under the jurisdiction of the Ministry of Public Works. This ultimately led to Utzon's resignation in 1966 (see below).

The cost of the project so far, even in October 1966, was still only $22.9 million, less than a quarter of the final $102 million cost. However, the projected costs for the design were at this stage much more significant.

The second stage of construction was progressing toward completion when Utzon resigned. His position was principally taken over by Peter Hall, who became largely responsible for the interior design. Other persons appointed that same year to replace Utzon were E. H. Farmer as government architect, D. S. Littlemore and Lionel Todd.

Following Utzon's resignation, the acoustic advisor, Lothar Cremer, confirmed to the Sydney Opera House Executive Committee (SOHEC) that Utzon's original acoustic design only allowed for 2000 seats in the main hall and further stated that increasing the number of seats to 3000 as specified in thebrief would be disastrous for the acoustics. According to Peter Jones, the stage designer, Martin Carr, criticised the "shape, height and width of the stage, the physical facilities for artists, the location of the dressing rooms, the widths of doors and lifts, and the location of lighting switchboards."
