The Co-Ordinator General of State Works originally gave the commission for the University of Queensland Agriculture and Entomology Building (known as Hartley Teakle Building) to Fred Scorer of the firm Scorer and Scorer on 17 March 1966. After Fred Scorer's untimely death in 1966, James Birrell purchased the Scorer and Scorer firm as part of setting up his own practice. He resigned as University Architect in late March 1966. The Co-Ordinator General approved Birrell taking over the commission for the Agriculture and Entomology Building. James Birrell and Partners were the architects for the building. The site chosen for the building was to the north-west of the Great Court on the western side of Mill road. The glass houses and veterinary buildings were built. Mayne Hall, now the UQ Art Museum and the Biological Science Library and Refect were not yet built. Front Drive still ran along the front of Main Building (now Forgan Smith).

The Agriculture and Entomology Building was designed to follow the site contours, was a 'c-shaped plan' and was designed to be built in three separate stages. Each stage was designed to be complete within themselves. Stage 1 was completed in February 1969; Stage 2 in May 1970; and Stage 3 in December 1970.
