The breakthrough became known as the “spherical solution.” Every shell would be cut from the surface of the same imaginary sphere. So the curved concrete pieces could be cast from a small set of repeating moulds.
In other words, Utzon turned an impossible building into a very large kit.
Work on the site had begun in 1959. The state paid for most of it with a special Opera House Lottery, so ordinary Sydneysiders bought tickets to build it.
Then politics arrived. After the 1965 election, the new Minister for Public Works, Davis Hughes, took control of the payments. He saw Utzon’s methods as chaotic, and he held back funds until Utzon could no longer pay his own staff.
On 28 February 1966, Utzon resigned. Crowds marched in Sydney to demand that he be brought back. It made no difference.
On 28 April 1966, he left Australia with his family. This is how far the building had come.

A team of Australian architects, led by Peter Hall, finished the interiors. Queen Elizabeth II opened the building on 20 October 1973.
It was ten years late. The final bill came to A$102 million… about fourteen times the original estimate.
In my finance years, I sat in meetings where projects were cancelled for far less. A spreadsheet would have called this a disaster. Then I first saw it from a ferry at dusk, the shells glowing over the water, and I understood the spreadsheet had been measuring the wrong thing.
This is the building Utzon never saw finished.

Time made peace with him. In 1999, the Opera House invited Utzon back as a design consultant, and he worked with them from Denmark. A reception room rebuilt to his design reopened in 2004 as the Utzon Room.
In 2003, he won the Pritzker Prize, the highest award in architecture.

In 2007, UNESCO named the building a World Heritage Site, while its architect was still alive. Utzon died in Copenhagen in November 2008. He never stood inside the finished house.

Nobody in 1957 knew how to build those shells. Utzon worked it out… and then left before anyone could thank him.
