Planning fallacy
The Sydney Opera House was expected to be completed in 1963. A scaled-down version opened in 1973, a decade later. The original cost was estimated at $7 million, but its delayed completion led to a cost of $102 million.
Perth Concert Hall (Western Australia)
The auditorium features a specially commissioned 3000-pipe organ surrounded by a 160-person choir gallery and an audience seating capacity of 1,729. The organ, individually designed, cost $100,000 and was commissioned by Ronald Sharp of Sydney, who was also responsible for the organ at the Sydney Opera House. The larger pipes for the organ were imported from the Netherlands. Don Bailey recollects that Ron Sharp was an ‘extraordinarily talented person, largely self-educated, who has to his credit the design and construction of a number of organs, mostly in New South Wales. A nine-foot Steinway orchestral concert grand piano (Model D) was also imported from West Germany for installation in the Hall.
