Rare Historical Photos Show The Construction Of Sydney Opera House

Before the Sydney Opera House became one of the world’s most recognized buildings, its future site at Bennelong Point was home to something far less dramatic — a tram shed. For years, the waterfront spot on Sydney Harbour served as a transit hub, with no hint of what was to come.

In 1956, the New South Wales government launched an international design competition to replace that tram shed with a world-class opera house. Architects from over 30 countries submitted entries. The following year, judges gathered to review the proposals and select a winner.

The winning design came from Jørn Utzon, a Danish architect who was relatively unknown at the time. His bold vision — featuring sweeping shell-shaped roof structures — stood apart from every other submission. He was awarded five thousand pounds for his design. Before any construction could begin, the old tram shed had to go.

Ground broke on the project in early 1959. Utzon himself was present at Bennelong Point to mark the start of what was expected to be a four-year, $7 million build.

The site preparation was a massive undertaking. Workers cleared and leveled the land throughout 1959, setting the foundation for one of the most structurally complex buildings of the 20th century.

By 1960, the concrete work was underway and the early skeleton of the structure was beginning to emerge. Aerial views from above the harbour revealed the first outlines of what would eventually become the building’s iconic shell-shaped roof forms.

The scale of the project required a large and constant workforce. Rather than commuting daily, many tradesmen lived on-site in caravans at Bennelong Point, keeping the work going without interruption.

The construction site became a familiar part of Sydney’s harbour landscape. Ships sailing past the point would pass directly alongside the growing structure, offering a striking contrast between the old world of ocean travel and the new architectural ambition rising from the shore.

By 1961, the project was already 47 weeks behind schedule. The complexity of Utzon’s design — particularly the geometry of the roof shells — proved far more difficult to engineer than originally anticipated. The four-year timeline was clearly not going to hold.

Managing the logistics of such a complicated build required a dedicated team of engineers and architects working closely together. Key figures on the executive committee met regularly to review plans and monitor progress.

One of the more remarkable engineering feats of the entire project was the construction of the building’s vast concourse. The structure was built using a folded concrete slab method, creating an unsupported span of 290 feet by 140 feet. When finished, the concourse alone would weigh 10,000 tons — roughly the same footprint as Sydney Town Hall.

On the ground level, carpenters and tradesmen handled the detailed work of forming the concrete that would shape the building’s interior spaces. By March 1962, workers were crafting the forms needed to pour concrete for stairways inside the minor hall.

Four years into construction, the Opera House was starting to look like something recognizable. The platforms and lower structures had taken shape, though the signature roof shells — the building’s defining feature — were still far from complete.

Progress remained painfully slow through 1963. The engineering problems tied to the roof geometry continued to eat into time and budget. What had been promised as a $7 million, four-year project was transforming into something far more expensive and complicated.

A major milestone came in December 1963 when sections of the roof were lifted into place. The shell structures that defined Utzon’s original vision were finally beginning to rise above the harbour.

By 1965, Utzon had been working on the project for nearly a decade — eight years since his design was selected and six years since construction began. He returned to the site as the shells continued their slow climb toward completion.

Work continued around the clock through 1965, with crews pressing forward on the roof and structural elements. There was no pause in the labor even as costs mounted and political pressure over the project’s budget grew louder in Canberra.

The political pressure eventually reached a breaking point. In February 1966, Minister for Public Works Davis Hughes cut off payments to Utzon’s office, effectively forcing the architect to resign from the project. The resignation sparked immediate public outrage. Students marched from the Opera House to Parliament House in protest just days later.

Utzon held a press conference shortly after his departure, displaying a scale model of the Opera House. He never returned to Australia and never saw the completed building in person.

With the exterior shell structures largely complete by late 1966, attention shifted to the interior — but Utzon had taken his interior design plans with him. The entire interior had to be redesigned from scratch by a new team of architects.

Architect Peter Hall was appointed to lead the redesign of the interiors. His appointment was not without controversy. University of Sydney students staged protests against the new architects taking over from Utzon.

Despite the controversy, construction pressed forward through 1966. The building’s exterior continued to grow, with the gleaming white tile-covered shells becoming an increasingly familiar sight over Sydney Harbour.

By January 1968, the project had crossed the ten-year mark with the roof shells still not fully complete. The scope of the engineering challenge was unlike anything builders had faced before — the shells required over one million ceramic tiles and precise geometric calculations that had taken years to resolve.

Peter Hall continued to oversee the interior work as the project moved into its final phase. Models of the completed building were used to visualize the interior halls and plan the acoustics and layout of each performance space.

As the 1960s ended, the finishing details became the focus. Consulting architects reviewed models of the main halls to finalize what the completed structure would look like from every angle.

In February 1972, Minister Davis Hughes — the same man who had forced Utzon out of the project six years earlier — toured the nearly finished concert hall alongside Premier Robert Askin. The building that had cost him a public scandal was almost done.

Construction was still wrapping up in October 1973, just weeks before the official opening. The final cost had ballooned to over $102 million — more than fourteen times the original estimate. Paul Robeson had performed for the construction workers on-site years earlier, becoming the first person to sing at the future opera house. Now the building was finally ready for its formal debut.

Queen Elizabeth II officially opened the Sydney Opera House on October 20, 1973 — fourteen years after the first shovel hit the ground at Bennelong Point. The ceremony marked the end of one of the most complicated, costly, and contested construction projects in Australian history.
