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 Western Arts Building was designed to be geometrically related to the existing surrounding buildings forming a visual relation across Mill Road. It was to sit back from the western end of Main Building (Forgan Smith), linked by a cloister. The pilot plan for the proposed Western Arts Building designed by Birrell was submitted to the Australian Universities Commission (A.U.C.) in 1965 and rejected. Birrell's design was a break from the original design by Hennessy and Hennessy who were eventually commissioned as architects for the Western Arts building (Mitchie Building) on 16 March 1967.
