PROJECT DESCRIPTION

A two-storey concrete building for the choirs of St George’s Cathedral and the Anglican Diocese of Perth. The lower floor includes prefabricated concrete curved beams internally and a prefabricated concrete external wall with vertical slots to provide light. U-shaped prefabricated columns support prefabricated concrete vaulted arches at the first floor level, forming a colonnade. On top of the vaulted units, there are two curved and sloping prefabricated concrete spires.

Judge's comment:

The dramatic colonnade entrance to this building, which fills a confined space between the cathedral and rectory, provides a dramatic visual impact by the use curved pre-cast white concrete elements with sandblast finish. The building is predominantly formed from off-site modular elements brought together to form internal curved beams, external walls with glazing to shed light to the lower floors and U-shaped columns supporting the vaulted arches up to two sloping and curved and sloping pre-cast concrete spires. This represents excellence in offsite structural component technology demonstrating an ability to achieve the shape and form of the architectural intent. The challenging pre-cast concrete structural shapes were created using a computer-generated mould system. The structural solution implemented demonstrates efficient use of material and speed of construction.
