Sydney Opera House.
The vaulted roof shells were designed by Utzon in collaboration with internationally renowned engineers Ove Arup & Partners with the final shape of the shells derived from the surface of a single imagined sphere. Each shell is composed of pre-cast rib segments radiating from a concrete pedestal and rising to a ridge beam. The shells are faced in glazed off-white tiles while the podium is clad in earth-toned, reconstituted granite panels. The glass walls are a special feature of the building, constructed according to the modified design by Utzon’s successor architect, Peter Hall
