An international competition for the design of the Opera House, won by Danish architect Jørn Utzon, was held in 1955 and work started in 1959. After many disagreements with the Department of Public Works of New South Wales, Utzon resigned from the project in 1966 at the mid-point of construction. The architectural duties passed to Peter Hall, E. H. Farmer, Lionel Todd and David Littlemore. Very sever cost overruns were apparent from th earliest stages of construction and the additional expenditure was alleviated by a series of public lotteries.
