1952 - Mr Peter McIntyre, Mr Bill Irwin and
Mr Kevin Borland with the award winning design model

Unusual shape of the building is created a very fascinating engineering design. It’s steel structure consists of truss system and some tensile elements. The weight of the trussed roof is bored by steel girders and stabilised by steel rods.
Concrete is used as base for stairs and also articulates the envelope of the building.
This picture shows steel trusses or girders connected via the braced steel plates with the roof trusses. The steel plates are also connected to the tension rods.
This picture shows pinned connection of the rods with the plates. Rods stabilise the uplift reaction of the trussed roof.
The rods are concreted in the ground (the detail is unfortunately covered by a steel cap)
The interior shows roof truss system with rigid connection. Interestingly, rafter is a truss that runs perpendicular to main structural trusses. The close up detail is shown below.
Additionally, the structure is braced by triangular steel tubes.
