How much money did the Sydney Opera House cost to build?
Sydney Opera House
The cost of the project so far, even in October 1966, was still only $22.9million,[39] less than a quarter of the final $102million cost. However, the projected costs for the design were at this stage much more significant.
Joseph Cahill
On 5 February 1959, Cahill signed the contract for the first stage of building works for the Opera House with the Chairman of Lendlease Corporation and Civil & Civic, Dick Dusseldorp, and the managing director of Brederos, Jan de Vries. On the occasion of the official start of building and the laying of the foundation plaque on 2 March 1959, Cahill declared that the Sydney Opera House, "will stand not merely as an outstanding example of modern architecture or even as a world famous opera house, but as a shrine in which the great artists of the world may be seen and heard and our own artists may display the flowering of Australian culture."
