The Geology Annex was submitted with the proposals for the Chemistry Annex and the Western Arts Building to the Australian Universities Commission (A.U.C.) in 1965, and rejected. It was to be situated behind the exiting Geology building, along Circular Drive (now named Staff House Road) between the Physics Annex and the bookshop. It was designed with basement, ground and first to fifth floors. It was resubmitted to the A.U.C. in 1966 and rejected again. This file comprises 16 plans for the proposed geology annex, including pilot plans, elevation, perspective views, floor plans for each level, as well a master planning conception drawing, massing considerations drawing and sketches of Geology annex view from Lake, the North East and from within the court (or intimate space as referred to on one of the concept drawings). One pilot plan dated March 1965.

The Geology Annex, the Chemistry Annexe and the Western Arts Building were part of a master planning concept. They shared the structural and construction concept developed by Birrell and Antony Tod (structural engineer). None of the proposals were built.
