The University of Queensland Faculty of Dentistry was formed in 1935 and was located at various locations throughout the city including Turbot Street. In the early 1960s there was a desire to have the Dental School transferred from its location in Turbot Street to the St. Lucia campus with Birrell writing a report in favour of this is in 1964. However the Australian Universities Commission did not support this idea. Rather they offered money to extend the Turbot Street facilities and to use space within the Physiology Building to house preclinical training. The new dental school at St. Lucia campus was not built.

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.

In 1923 Dr James O'Neil Mayne and Mary Emelia Mayne (siblings) donated to the University of Queensland 693 acres of land at Moggill (now Pinjarra Hills) on the Brisbane River. In 1952 the Veterinary School set up an experimental farm at Moggill. At the time it was referred to as Moggill Farm.

In 1957, the Vice Chancellor of the University of Queensland, Professor James Douglas Story, proposed a regional university college be established. This desire came to fruition on 27 February 1961 when the University College of Townsville was opened. This college became the James Cook University of North Queensland on 29 April 1970 and is now known as James Cook University.

In 1965 430 acres of bushland was set aside for a new campus in Brisbane's south in the suburb Nathan. Initially this was to be a University college of the University of Queensland but by September 1971 it was established as Griffith University.

Birrell was asked by the Co-Ordinator General of the Public Works to draw up plans for both colleges. The majority of these plans have the title block for the University of Queensland and James Birrell as the UQ Architect. This subseries contains plans for the University Colleges, Townsville (22 plans) and Mt Gravatt (23 plans).

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.

The Boat Club of the University of Queensland was established in 1911. Referred to as a shed in the working drawings, Birrell designed a simple building to function as an amenities building for The Boat Club. These plans were designed for submission to the Australian Universities Commission in 1965. It is located between Sir William Macgregor Drive and the Brisbane River. It is now called the Eric Freeman Boathouse. Eric Freeman, attained a Bachelor of Engineering from the University of Queensland and was a valued member of the Varsity Eight (rowing) from 1921 to 1924. This file includes:
[Item 1] Boat garage sketch plan (May 1964).
[Item 2] Portal frame diagram (29 Feb 1966).

10 plans, ink line drawings on tracing paper, for renovations to Main Building (now known as Forgan Smith Building). Stage 1 comprises 5 drawings for the Law and the Thomas Thatcher Memorial Libraries with drawing numbers A1/54 to A1/58, dated Aug to Sep 1965. The Thatcher Library, established in 1948, provided services for distance education and closed in 1993. Stage 2 comprises 3 drawings for the area between the Library and Arts entrance with drawing numbers A1/59 to A1/61. There is a plan for the Language laboratory which has no job number or details in title block. The final plan is Job A1/32 Proposed mezzanine floor to printery (Library basement): Architectural plan, ink line drawing on tracing paper, 38 x 70 cm; title block has University Architect J.P. Birrell; Job/drawing number A1/32; no date.

The Shapcott press was on the lower ground floor of Main Library. During the extension to Main Library there was discussion that the printery could be housed on the bottom floor of the Main Building. This last plan seems to reflect that idea. When Main Library was extended the Printery was moved to the Industrial Centre Building, located on the corner of Services Road and Hood Street.

Main Library was part of the Great Court buildings designed by Hennessy and Hennessy in 1935-1936. It consisted of two floors with a glass ceiling in the light well in the centre. Main Building was designed to be extended with an additional three floors, with high ceilings and a large light well in the centre. When the Library had insufficient space for students and books it was decided to go ahead with the extension of three more floors, as specified by Hennessy and Hennessy. Birrell proposed five additional floors instead of the three, the installation of passenger lifts, fluorescent lighting, and air-conditioning. Birrell was responsible for the internal arrangement and finishes. This file comprises 15 plans for alterations and additions to Main Library. Includes: sketch of lower ground floor (now Level 1), working drawings for 1st to 5th floors (now Level 3 to Level 7), stair details and compactus shelving.

Main Library was later known as Undergraduate Library; with the construction of Central Library in 1971 its name was changed to Duhig Building; and later, around 2000, to Duhig Tower.
