 In 1972, the brief and a development plan, prepared by the Government Architect, were tabled in Parliament.After a review, the Treasury recommended the deletion of the swimming pool, but Premier Robert Askin rejected this advice.Unlike the proposed demolition proposed in the 1964 scheme, the 1972 development plan required the new building to be constructed entirely within the boundary of the existing site, while leaving space for future additions to the State Library of New South Wales.
