Built at a total cost of $ 102 million , the 600ft long , 394ft wide Sydney Opera House is now one of the most famous buildings within Australia , and has also received a 4-star Green Star Performance rating from the Green Building Council of Australia ( GBCA ).

Designed by Danish architect Jørn Utzon and completed by Peter Hall post his resignation , the expressionist build incorporates several precast concrete rib ( or shell like ) structures , built by Hornibrook Group Pty Ltd ( now part of Bilfinger ), which form the iconic roof design , with over one million different coloured tiles , created by Swedish firm Höganäs AB . The build is also supported through the implementation of over 550 concrete piers .

The performing arts venue took around 20 years to complete and encompasses several performance areas , becoming home to a number of performance companies , dining and retail outlets .
