The Sydney Opera House is a multi-venue performing arts centre in Sydney, Australia. It is one of the 20th century's most famous and distinctive buildings.[3]

Designed by Danish architect Jørn Utzon, the building was formally opened on 20 October 1973[4] after a gestation beginning with 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 is often overshadowed by circumstances that followed, including cost and scheduling overruns as well as the architect's ultimate resignation.[5]

The building and its surrounds occupy the whole of Bennelong Point in Sydney Harbour, between Sydney Cove and Farm Cove, adjacent to the Sydney central business district and the Royal Botanic Gardens, and close by the Sydney Harbour Bridge.

Though its name suggests a single venue, the building comprises multiple performance venues which together are among the busiest performing arts centres – hosting well over 1,500 performances annually, attended by more than 1.2 million people.[6] Performances are presented by numerous performing artists, including four resident companies: Opera Australia, The Australian Ballet, the Sydney Theatre Company and the Sydney Symphony Orchestra. As one of the most popular visitor attractions in Australia, more than eight million people visit the site annually, and approximately 350,000 visitors take a guided tour of the building each year.[7] The building is managed by the Sydney Opera House Trust, an agency of the New South Wales State Government.

On 28 June 2007, the Sydney Opera House became a UNESCO World Heritage Site.[8]

Description

The facility features a modern expressionist design, with a series of large precast concrete "shells",[9] each composed of sections of a sphere of 75.2 metres (246 ft 8.6 in) radius,[10] 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.[11] 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.[12]

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.[13]

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 facilities

The Sydney Opera House includes a number of performance venues:[14]

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.

Other facilities

The building also houses a recording studio, cafes, restaurants, bars and retail outlets. 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.

Construction history

Origins

Planning began in the late 1940s, when Eugene Goossens, the Director of the NSW State Conservatorium of Music, lobbied for 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 NSW 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 northwest of the CBD.[19]

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.[20]

The winner, announced in 1957, was Jørn Utzon, a Danish architect. According to legend the Utzon design was rescued from a final cut of 30 "rejects" by the noted Finnish American architect Eero Saarinen. The prize was £5,000.[21] Utzon visited Sydney in 1957 to help supervise the project.[22] His office moved to Palm Beach, Sydney in February 1963.[23]

Utzon received the Pritzker Architecture Prize, architecture's highest honour, in 2003.[24] The Pritzker Prize citation read:

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.

Design and construction

The Fort Macquarie Tram Depot, occupying the site at the time of these plans, was demolished in 1958 and construction began in March 1959. It was built in three stages: stage I (1959–1963) consisted of building the upper podium; stage II (1963–1967) the construction of the outer shells; stage III (1967–1973) interior design and construction.

Stage I: Podium

Stage I commenced on 2 March 1959 with the construction firm Civil & Civic, monitored by the engineers Ove Arup and Partners.[25] The government had pushed for work to begin early, fearing that funding, or public opinion, might turn against them. However, Utzon had still not completed the final designs. Major structural issues still remained unresolved. By 23 January 1961, work was running 47 weeks behind,[25] 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 was the fact that the podium columns were not strong enough to support the roof structure, and had to be re-built.[26]

Stage II: Roof

The shells of the competition entry were originally of undefined geometry,[27] 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 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 shells involved one of the earliest uses of computers in structural analysis, to understand the complex forces to which the shells would be subjected.[28] 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 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, 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."[29] 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 the geometry of the shells, from parabolas to ellipsoids and spheres."[28] Yuzo Mikami, a member of the design team, presents an opposite view in his book on the project, Utzon's Sphere.[30][31] It is unlikely that the truth will ever be categorically known, but there is a clear consensus that the design team worked very well indeed for the first part of the project and that Utzon, Arup, and Ronald Jenkins (partner of Ove Arup and Partners responsible for the Opera House project) all played a very significant part in the design development.[32]

As Peter Murray states in The Saga of the Sydney Opera House:[26]

... the two men—and their teams—enjoyed a collaboration that was remarkable in its fruitfulness and, despite many traumas, was seen by most of those involved in the project as a high point of architect/engineer collaboration.

The design of the roof was tested on scale models in wind tunnels at Southampton University and later NPL in order 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.[33][34]

The shells were constructed by Hornibrook Group Pty Ltd,[35] who were also responsible for construction in Stage III. Hornibrook manufactured the 2400 precast ribs and 4000 roof panels in an on-site factory and also developed the construction processes.[26] The achievement of this solution avoided the need for expensive formwork construction by allowing the use of precast units (it also allowed the roof tiles to be prefabricated in sheets on the ground, instead of being stuck on individually at height). Ove Arup and Partners' site engineer supervised the construction of the shells, which used an innovative adjustable steel-trussed "erection arch" to support 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 Ministry's criticism of the project's costs and time,[36] 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 $22.9 million,[37] 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 allowed for only 2000 seats in the main hall and further stated that increasing the number of seats to 3000 as specified in the brief 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."[38]

Completion and cost

The Opera House was formally completed in 1973, having cost $102 million.[41] H.R. "Sam" Hoare, the Hornibrook director in charge of the project, provided the following approximations in 1973: Stage I: podium Civil & Civic Pty Ltd approximately $5.5m. Stage II: roof shells M.R. Hornibrook (NSW) Pty Ltd approximately $12.5m. Stage III: completion The Hornibrook Group $56.5m. Separate contracts: stage equipment, stage lighting and organ $9.0m. Fees and other costs: $16.5m.

The original cost and scheduling estimates in 1957 projected a cost of £3,500,000 ($7 million) and completion date of 26 January 1963 (Australia Day).[28] In actuality, the project was completed ten years late and 1,457% over budget in real terms.

Utzon and his resignation

The building illuminated at night

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.[42] 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 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 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 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."[43] His new Minister for Public Works, Davis Hughes, was even less sympathetic. Elizabeth Farrelly, Australian architecture critic, has written 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 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.[43]

Differences ensued. One of the first was that Utzon believed the clients should receive information on all aspects of 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 the New South Wales government insisting contracts be put out to tender.[26]

Utzon was highly reluctant to respond to questions or criticism from the client's Sydney Opera House Executive Committee (SOHEC).[44] 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 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"[45] and: "The Opera House could become the world's foremost contemporary masterpiece if Utzon is given his head."

In October 1965, Utzon gave Hughes a schedule setting out the completion dates of parts of his work for stage III. Utzon was at this time working closely with Ralph Symonds, a manufacturer of plywood based in Sydney and highly regarded by many, despite an Arup engineer warning that Ralph Symonds's "knowledge of the design stresses of plywood, was extremely sketchy" and that the technical advice was "elementary to say the least and completely useless for our purposes." Australian architecture critic Elizabeth Farrelly has referred to Ove Arup's project engineer Michael Lewis as having "other agendas".[43] In any case, Hughes shortly after withheld permission for the construction of plywood prototypes for the interiors, and the relationship between Utzon and the client never recovered. By February 1966, Utzon was owed more than $100,000 in fees.[46] 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."[47]

Utzon left the project on 28 February 1966. He said that Hughes's refusal to pay him any fees and the lack of collaboration caused his resignation and later famously described the situation as "Malice in Blunderland". 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 was in the right and who was in the wrong. The Sydney Morning Herald initially opined: "No architect in the world has enjoyed greater freedom than Mr Utzon. 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, the Herald offered the view that:[48] "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 the way for the immensely complex geometries of some modern architecture. The design was one of the first examples of the use of computer-aided design to design complex shapes. 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 is also one of the first in the world to use araldite to glue the precast structural elements together and proved the concept for future use.

It was also a first in mechanical engineering. Another Danish firm, Steensen Varming, was responsible for designing the new air-conditioning plant, the largest in Australia at the time, supplying over 600,000 cubic feet (17,000 m3) of air per minute,[49] using the innovative idea of harnessing the harbour water to create a water-cooled heat pump system that is still in operation today.[50]

Architectural design role of Peter Hall

After the resignation of Utzon, the Minister for Public Works, Davis Hughes, and the Government Architect, Ted Farmer, organised a team to bring the Sydney Opera House to completion. The architectural work was divided between three appointees who became the Hall, Todd, Littlemore partnership. David Littlemore would manage construction supervision, Lionel Todd contract documentation, while the crucial role of design became the responsibility of Peter Hall.[51]

Peter Hall (1931–1995) completed a combined arts and architecture degree at Sydney University. Upon graduation a travel scholarship enabled him to spend twelve months in Europe during which time he visited Utzon in Hellebæk.[52] Returning to Sydney, Hall worked for the Government Architect, a branch of the NSW Public Works Department. While there he established himself as a talented design architect with a number of court and university buildings, including the Goldstein Hall at the University of New South Wales, which won the Sir John Sulman Medal in 1964.

Hall resigned from the Government Architects office in early 1966 to pursue his own practice. When approached to take on the design role, (after at least two prominent Sydney architects had declined), Hall spoke with Utzon by phone before accepting the position. Utzon reportedly told Hall: he (Hall) would not be able to finish the job and the Government would have to invite him back.[53] Hall also sought the advice of others, including architect Don Gazzard who warned him acceptance would be a bad career move as the project would "never be his own".[54]

Hall agreed to accept the role on the condition there was no possibility of Utzon returning. Even so, his appointment did not go down well with many of his fellow architects who considered that no one but Utzon should complete the Sydney Opera House.[52] Upon Utzon's dismissal, a rally of protest had marched to Bennelong Point. A petition was also circulated, including in the Government Architects office. Peter Hall was one of the many who had signed the petition that called for Utzon's reinstatement.[52]

When Hall agreed to the design role and was appointed in April 1966, he imagined he would find the design and documentation for the Stage III well advanced. What he found was an enormous amount of work ahead of him with many aspects completely unresolved by Utzon in relation to seating capacity, acoustics and structure.[55] In addition Hall found the project had proceeded for nine years without the development of a concise client brief. To bring himself up to speed, Hall investigated concert and opera venues overseas and engaged stage consultant Ben Schlange and acoustic consultant Wilhelm Jordan, while establishing his team. In consultation with all the potential building users the first Review of Program was completed in January 1967. The most significant conclusion reached by Hall was that concert and opera were incompatible in the same hall.[56] Although Utzon had sketched ideas using plywood for the great enclosing glass walls their structural viability was unresolved when Hall took on the design role.[57] With the ability to delegate tasks and effectively coordinate the work of consultants, Hall guided the project for over five years until the opening day in 1973.

A former Government Architect, Peter Webber, in his book Peter Hall: the Phantom of the Opera House, concludes: when Utzon resigned no one was better qualified (than Hall) to rise to the challenge of completing the design of the Opera House.[58]

Opening

Tourists observing the Opera House.

The Sydney Opera House was formally opened by Elizabeth II, Queen of Australia, on 20 October 1973. A large crowd attended. Utzon was not invited to the ceremony, nor was his name mentioned. The opening was televised and included fireworks and a performance of Beethoven's Symphony No. 9.[59]

Performance firsts

During the construction phase, lunchtime performances were often arranged for the workers, with American vocalist Paul Robeson the first artist to perform, in 1960.

Various performances were presented prior to the official opening:

After the opening:

Reconciliation with Utzon; building refurbishment

The Utzon Room: rebuilt to a design (and endowed with an original tapestry) by Utzon

In the late 1990s, the Sydney Opera House Trust resumed communication with Utzon in an attempt to effect a reconciliation and to secure his involvement in future changes to the building. In 1999, he was appointed by the Trust as a design consultant for future work.[64]

In 2004, the first interior space rebuilt to an Utzon design was opened, and renamed "The Utzon Room" in his honour. It contains an original Utzon tapestry (14.00 x 3.70 metres) called Homage to Carl Philipp Emmanuel Bach.[65] In April 2007, he proposed a major reconstruction of the Opera Theatre, as it was then known.[66] Utzon died on 29 November 2008.[67]

A state memorial service, attended by Utzon's son Jan and daughter Lin, celebrating his creative genius, was held in the Concert Hall on 25 March 2009 featuring performances, readings and recollections from prominent figures in the Australian performing arts scene.

Refurbished Western Foyer and Accessibility improvements were commissioned on 17 November 2009, the largest building project completed since Utzon was re-engaged in 1999. Designed by Utzon and his son Jan, the project provided improved ticketing, toilet and cloaking facilities. New escalators and a public lift enabled enhanced access for the disabled and families with prams. The prominent paralympian athlete Louise Sauvage was announced as the building's "accessibility ambassador" to advise on further improvements to aid people with disabilities.[68]

On 29 March 2016, an original 1959 tapestry by Le Corbusier (2.18 x 3.55 metres), commissioned by Utzon to be hung in the Sydney Opera House and called Les Dés Sont Jetés (The Dice Are Cast), was finally unveiled in situ after being owned by the Utzon family and held at their home in Denmark for over 50 years. The tapestry was bought at auction by the Sydney Opera House in June 2015. It now hangs in the building's Western Foyer and is accessible to the public.

Public and commemorative events

In 1993, Constantine Koukias was commissioned by the Sydney Opera House Trust in association with REM Theatre to compose Icon, a large-scale music theatre piece for the 20th anniversary of the Sydney Opera House [69]

During the 2000 Summer Olympics, the venue served as the focal point for the triathlon events. The event had a 1.5 km (0.9 mi) swimming loop at Farm Cove, along with competitions in the neighbouring Royal Botanical Gardens for the cycling and running portions of the event.[70] In 2012, Louise Herron was appointed as the first female chief executive officer of the Sydney Opera House in its history.

The Sydney Opera House sails formed a graphic projection-screen in a lightshow mounted in connection with the International Fleet Review in Sydney Harbour on 5 October 2013.[71]

On 31 December 2013, the venue's 40th anniversary year, a New Year firework display was mounted for the first time in a decade.[72]
