Demonstration model of the opera house, Sydney

SydneyOperaHouse
 

The roof structure of Utzon’s competition-winning design could not be built as planned as the shell forms of the roof were irregular and structurally unsound. Utzon’s solution was to take all the forms from a single sphere, as shown in this demonstration model. This allowed all the shell components to be calculated and then prefabricated.
