There are two architectural drawings, ink on paper, with the title The Union which may form part of the pilot plans for an extension to The Union Building which Birrell designed in 1962. There are 14 drawings for the Master Planning Report upon the Student Union Precinct University of Queensland, which was produced by Birrell and assistant architect Richard Stringer. This report was submitted to the Buildings and Grounds Committee in March 1966. 12 of these 14 drawings have the University of Queensland title block with J.P. Birrell as University Architect. Included with these drawings, which form part of the master plan for the precinct, are several designs for a Union Theatre. There are two pencil drawings related to the Union Theatre, without title, date, or creators. All plans are undated.

Prior to the construction of the J.D. Story Administration Building, University administration facilities had been housed within Main Building (now know as the Forgan Smith Building). Main Building had undergone many alterations in response to the changing needs of the university administration. In 1959 the Senate decided a new Administration Building should be built. Other building priorities delayed designs being drawn up. In 1962 plans were submitted to the Australian Universities Commission (A.U.C.). Changes requested by the A.U.C. delayed construction which was to be a two stage process: Stage One was completed in October 1965 and Stage Two in October 1966. Plans include: site plans, window details, detail of senate table, floor plans, electrical services plans, roof plans.

There are 6 volumes (sets/presentation volume/office copy sets) with plans as well as individual plans; the total number of plans for this building in this subseries are 281. Not all have been created by James Birrell.
