61-839: The Sydney Opera House Trust operates and maintains the Sydney Opera House in Sydney for the Government of New South Wales in Australia . The Trust operates as one of the State's premier cultural institutions within the Create NSW portfolio. It is constituted as a body corporate under the Sydney Opera House Trust Act 1961 . It has 10 members appointed by the Governor of New South Wales on
122-453: A cost of £ 3,500,000 ($ 7 million) and completion date of 26 January 1963 ( Australia Day ). In reality, the project was completed ten years late and 1,357% over budget in real terms. In 1972, a construction worker was fired, leading the BLF -affiliated workers to demand his rehiring and a 25% wage increase. In response to this, all the workers were fired, and in revenge the workers broke into
183-467: A large payment for their troubles. Before the Sydney Opera House competition, Jørn Utzon had won seven of the 18 competitions he had entered but had never seen any of his designs built. Utzon's submitted concept for the Sydney Opera House was almost universally admired and considered groundbreaking. The Assessors Report of January 1957 stated: The drawings submitted for this scheme are simple to
244-523: A masterpiece of 20th-century architecture. Designed by Danish architect Jørn Utzon and completed by an Australian architectural team headed by Peter Hall , the building was formally opened by Queen Elizabeth II on 20 October 1973, 16 years after Utzon's 1957 selection as winner of an international design competition. The Government of New South Wales , led by the premier , Joseph Cahill , authorised work to begin in 1958 with Utzon directing construction. The government's decision to build Utzon's design
305-638: A member of the Sydney Opera House Executive Committee, states: "Utzon came up with an idea of making all the shells of uniform curvature throughout in both directions." Peter Jones, the author of Ove Arup's biography, states that "the architect and his supporters alike claimed to recall the precise eureka moment ...; the engineers and some of their associates, with equal conviction, recall discussion in both central London and at Ove's house." He goes on to claim that "the existing evidence shows that Arup's canvassed several possibilities for
366-417: A philistine, he had been exposed before Parliament and dumped as Country Party leader for 19 years of falsely claiming a university degree. The Opera House gave Hughes a second chance. For him, as for Utzon, it was all about control; about the triumph of homegrown mediocrity over foreign genius. Differences ensued. One of the first was that Utzon believed the clients should receive information on all aspects of
427-627: A recording studio, retail shops, cafes, restaurants, bars including the Opera Bar and Opera Kitchen. Guided tours are available, including a frequent tour of the front-of-house spaces, and a daily backstage tour that takes visitors backstage to see areas normally reserved for performers and crew members. Planning began in the late 1940s when Eugene Goossens , the Director of the New South Wales State Conservatorium of Music , lobbied for
488-613: A single building, the two-storey Government House. In the early 1790s, the Aboriginal man Woollarawarre Bennelong — employed as a cultural interlocutor by the British—persuaded Governor of New South Wales , Arthur Phillip, to build a brick hut for him on the point, giving it its colonial name. In December 1798, a half-moon battery was constructed at the extreme northern end of the Point, mounted with guns from HMS Supply . In
549-460: 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 and 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
610-485: A suitable venue for large theatrical productions. The normal venue for such productions, the Sydney Town Hall , was not considered large enough. By 1954 Goossens succeeded in gaining the support of New South Wales Premier Joseph Cahill , who called for designs for a dedicated opera house. It was also Goossens who insisted that Bennelong Point be the site: Cahill had wanted it to be on or near Wynyard Railway Station in

The building and its surrounds occupy the whole of Bennelong Point on Sydney Harbour , between Sydney Cove and Farm Cove , adjacent to the Sydney central business district and the Royal Botanic Gardens , and near to the Sydney Harbour Bridge . The building comprises multiple performance venues, which together host well over 1,500 performances annually, attended by more than 1.2 million people. Performances are presented by numerous performing artists, with many resident companies such as Opera Australia ,
793-462: Is supported on 588 concrete piers sunk as much as 25 m (82 ft) below sea level. The highest roof point is 67 metres above sea-level which is the same height as that of a 22-storey building. The roof is made of 2,194 pre-cast concrete sections, which weigh up to 15 tonnes each. 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

The Sydney Opera House includes a number of performance venues: 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. The building also houses

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
976-513: The Herald offered the view that: "It was not his [Utzon's] fault that a succession of Governments and the Opera House Trust should so signally have failed to impose any control or order on the project ... his concept was so daring that he himself could solve its problems only step by step ... his insistence on perfection led him to alter his design as he went along." The Sydney Opera House opened
1037-672: The Sydney Theatre Company and the Sydney Symphony Orchestra . As one of the most popular visitor attractions in Australia, the site is visited by more than eight million people annually, and approximately 350,000 visitors take a guided tour of the building each year. The building is managed by the Sydney Opera House Trust , an agency of the New South Wales State Government. On 28 June 1998
1098-824: The 1961 act comprised 17 trustees: the Premier Bob Heffron or the Minister for Public Works ( Norm Ryan ; as president), the Lord Mayor of Sydney ( Harry Jensen ; as vice-president), and 15 'nominated trustees': Stanley Haviland CBE (chairman), Edward William Adams, Clarence Henry Woodward Arthy, Professor Henry Ingham Ashworth, Doris Fitton OBE , John Glass CBE , Sir Bernard Heinze , Neil Hutchison, Hon. James Denis Kenny , Erik Langker OBE , Dr Nicolai Malko , Charles Moses CBE , Dr Cobden Parkes CBE , Dr Lloyd Maxwell Ross, and Dr Harold Wyndham . The Trust consists of ten members in total, including

The achievement of this solution avoided the need for expensive formwork construction by allowing the use of precast units and it also allowed the roof tiles to be prefabricated in sheets on the ground, instead of being stuck on individually at height. The tiles themselves were manufactured by

1281-558: The Ministry's criticism of the project's costs and time, along with their impression of Utzon's designs being impractical, this ultimately led to his resignation in 1966 (see below). The cost of the project so far, even in October 1966, was still only A$ 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

Utzon was highly reluctant to respond to questions or criticism from the client's Sydney Opera House Executive Committee (SOHEC). However, he was greatly supported throughout by a member of the committee and one of the original competition judges, Harry Ingham Ashworth . Utzon was unwilling to compromise on some aspects of his designs that

It is made from clay with a small percentage of crushed stone. Ove Arup and Partners' site engineer supervised the construction of the shells, which used an innovative adjustable steel-trussed "erection arch" (developed by Hornibrook's engineer Joe Bertony ) to support
1525-728: The Sydney Opera House became a UNESCO World Heritage Site , having been listed on the (now defunct) Register of the National Estate since 1980, the National Trust of Australia register since 1983, the City of Sydney Heritage Inventory since 2000, the New South Wales State Heritage Register since 2003, and the Australian National Heritage List since 2005. The Opera House was also a finalist in

The Sydney Opera House Trust was established by the Sydney Opera House Trust Act 1961 , which came into effect from 14 March 1961, replacing the Sydney Opera House Executive Committee, which since 1954 had investigated the location and design competition. The first trust appointed under

Stage I started on 2 March 1959 with the construction firm Civil & Civic , monitored by the engineers Ove Arup and Partners . The government had pushed for work to begin early, fearing that funding, or public opinion, might turn against them. But Utzon had still not completed
1708-429: The clients wanted to change. Utzon's ability was never in doubt, despite questions raised by Davis Hughes, who attempted to portray Utzon as an impractical dreamer. Ove Arup actually stated that Utzon was "probably the best of any I have come across in my long experience of working with architects" and: "The Opera House could become the world's foremost contemporary masterpiece if Utzon is given his head." In 1965 Utzon
1769-399: The competition were: Professor Henry Ashworth ( University of Sydney ), Cobden Parkes ( New South Wales Government Architect ); Professor Leslie Martin (Professor of Architecture of Cambridge University and architect of Royal Festival Hall 1951) and American architect Eero Saarinen . The winner, announced in Sydney on 29 January 1957, was Danish architect Jørn Utzon . Utzon's design
1830-761: The completion of the final plans. After the 1965 election of the Liberal Party, with Robert Askin becoming Premier of New South Wales , the relationship of client, architect, engineers and contractors became increasingly tense. Askin had been a "vocal critic of the project prior to gaining office." His new Minister for Public Works, Davis Hughes , was even less sympathetic. Elizabeth Farrelly , an Australian architecture critic, wrote that: at an election night dinner party in Mosman, Hughes' daughter Sue Burgoyne boasted that her father would soon sack Utzon. Hughes had no interest in art, architecture or aesthetics. A fraud, as well as

Workers' control was applied to the site for five weeks as the construction workers worked 35 hours a week with improved morale, more efficient organization and fewer people skipping work. The workers agreed to end their work-in when management agreed to give them a 25% wage increase, the right to elect their foremen, four weeks annual leave and

1952-449: The costs or work involved in design and construction. Tensions between the client and the design team grew further when an early start to construction was demanded despite an incomplete design. This resulted in a continuing series of delays and setbacks while various technical engineering issues were being refined. The building was unique, and the problems with the design issues and cost increases were exacerbated by commencement of work before
2013-417: The design and construction through his practice, while the clients wanted a system (notably drawn in sketch form by Davis Hughes) where architect, contractors, and engineers each reported to the client directly and separately. This had great implications for procurement methods and cost control, with Utzon wishing to negotiate contracts with chosen suppliers (such as Ralph Symonds for the plywood interiors) and
2074-447: The design team found a solution to the problem: the shells all being created as sections from a sphere. This solution allows arches of varying length to be cast in a common mould, and a number of arch segments of common length to be placed adjacent to one another, to form a spherical section. With whom exactly this solution originated has been the subject of some controversy. It was originally credited to Utzon. Ove Arup's letter to Ashworth,
2135-473: The different roofs before completion. On 6 April 1962, it was estimated that the Opera House would be completed between August 1964 and March 1965. 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. Due to

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
2257-485: The final designs. Major structural issues still remained unresolved. By 23 January 1961, work was running 47 weeks behind, mainly because of unexpected difficulties (inclement weather, unexpected difficulty diverting stormwater, construction beginning before proper construction drawings had been prepared, changes of original contract documents). Work on the podium was finally completed in February 1963. The forced early start led to significant later problems, not least of which
2318-471: The firm GBQC Architects. The grand prize was 5,000 Australian pounds . Utzon visited Sydney in 1957 to help supervise the project. His office moved to Palm Beach , Sydney in February 1963. Utzon received the Pritzker Architecture Prize , architecture's highest honour, in 2003. The Pritzker Prize citation read: There is no doubt that the Sydney Opera House is his masterpiece.

In March 1966, Hughes offered him a subordinate role as "design architect" under a panel of executive architects, without any supervisory powers over the House's construction, but Utzon rejected this. Utzon left the country never to return. Following the resignation, there was great controversy about who

An international design competition was launched by Cahill on 13 September 1955 and received 233 entries, representing architects from 32 countries. The criteria specified a large hall seating 3,000 and a small hall for 1,200 people, each to be designed for different uses, including full-scale operas, orchestral and choral concerts, mass meetings, lectures, ballet performances, and other presentations. The jury for

The entire area was leveled to create a low platform and to provide suitable stone for the construction of Fort Macquarie . While the fort was being built, a large portion of the rocky escarpment at Bennelong Point was also cut away to allow a road to be built around
2928-517: The point of being diagrammatic. Nevertheless, as we have returned again and again to the study of these drawings, we are convinced that they present a concept of an Opera House which is capable of becoming one of the great buildings of the world. For the first stage, Utzon worked successfully with the rest of the design team and the client, but, as the project progressed, the Cahill government insisted on progressive revisions. They also did not fully appreciate
2989-495: The roof was tested on scale models in wind tunnels at University of Southampton and later NPL to establish the wind-pressure distribution around the roof shape in very high winds, which helped in the design of the roof tiles and their fixtures. The immensely complex design and construction of the shells was completed by Hornibrook Group Pty Ltd , who were also responsible for construction in Stage III. Hornibrook manufactured

The computer system was also used in the assembly of the arches. The pins in the arches were surveyed at the end of each day, and the information was entered into the computer so the next arch could be properly placed the following day. In mid-1961,

The design techniques developed by Utzon and Arup for the Sydney Opera House have been further developed and are now used for architecture, such as works of Gehry and blobitecture , as well as most reinforced concrete structures. The design

Few clients have been more patient or more generous than the people and the Government of NSW. One would not like history to record that this partnership was brought to an end by a fit of temper on the one side or by a fit of meanness on the other." On 17 March 1966,
3294-428: Was no repetition in any of the roof forms, the construction of precast concrete for each individual section would possibly have been even more expensive. 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 design work on

The island was located on the tip of the eastern arm of Sydney Cove and was separated from the mainland at high tide. For a brief period in 1788, this relatively isolated protrusion into Port Jackson was called Cattle Point as it
3416-437: Was owed more than $ 100,000 in fees. Hughes then withheld funding so that Utzon could not even pay his own staff. The government minutes record that following several threats of resignation, Utzon finally stated to Davis Hughes: "If you don't do it, I resign." Hughes replied: "I accept your resignation. Thank you very much. Goodbye." Utzon left the project on 28 February 1966. He said that Hughes's refusal to pay him any fees and

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 allowed for only 2,000 seats in

The shells of the competition entry were originally of undefined geometry, but, early in the design process, the "shells" were perceived as a series of parabolas supported by precast concrete ribs. However, engineers Ove Arup and Partners were unable to find an acceptable solution to constructing them. The formwork for using in-situ concrete would have been prohibitively expensive, and, because there

Australian architecture critic Elizabeth Farrelly has referred to Ove Arup's project engineer Michael Lewis as having "other agendas". By February 1966, Utzon
