A reworking of London's Crystal Palace, the plan for the Garden Palace was similar to that of a large cathedral, having a long hall with lower aisle on either side, like a nave, and a transept of similar form, each terminating in towers and meeting beneath a central dome. The successful contractor was John Young, a highly experienced building contractor who had worked on the Crystal Palace for The Great Exhibition of 1851 and locally on the General Post Office and Exhibition Building at Prince Alfred Park.
