The Opera house
THE COSTRUCTION
The original requirements set out in the competition were for two multi-use halls. In the process of its realisation, after Utzon’s departure in 1966, these requirements were lost sight of and Grand Opera was abandoned in the Major Hall, with opera relegated to the Small Hall, which was intended as a theatre.
The building covers about 1.8 hectares (4.5 acres) of its 2.2 hectare (5.5 acre) site. It has about 4.5 hectares (11 acres) of usable floor space.
It is approximately 185 m (611 ft) long and 120m (380 ft) wide at its widest point. The highest roof vault (above the Concert Hall) is 67m (221 ft) above sea level.
