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.
Oslo Opera House
In 1999, after a long national debate, the Norwegian legislature decided to construct a new opera house in the city. A design competition was held and, of the 350 entries received, the judges chose that of Snøhetta. Construction started in 2003 and was completed in 2007, ahead of schedule and 300 million NOK (~US$52 million) under its budget of 4.4 billion NOK (~US$760 million). The gala opening on 12 April 2008 was attended by His Majesty King Harald, Queen Margrethe II of Denmark and President Tarja Halonen of Finland and other leaders. During the first year of operation, 1.3 million people passed through the building's doors.
