Sydney Opera House
The cost of the project so far, even in October 1966, was still only $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.
Garden Palace
The Garden Palace was a large, purpose-built exhibition building constructed to house the Sydney International Exhibition in 1879 in Sydney, Australia. It was designed by James Barnet and constructed by John Young, at a cost of ₤191,800 in only eight months. This was largely due to the importation from England of electric lighting, which enabled work to be carried out around the clock.
