Botanical Gardens Conservatory, Adelaide

The bicentennial project houses a tropical rainforest in its natural climactic environment, consisting of a three dimensional steel frame – 100m long, 47m wide and 27m high.

Erection of all 28 trusses, which carried 2092 glass panes and mechanical systems such as hydraulic spray pipes and hoisting apparatus to provide maintenance access, was achieved without a single breakage.

Within the structure, suspended walkways and viewing platforms allow visitors to look down into a natural setting more reminiscent of a tropical island than a garden in the southern state.
