South Lawn car park, parking structure in Melbourne, Australia

The South Lawn car park is a parking garage at the University of Melbourne built in 1971–72. It consists of reinforced concrete shells with parabolic profiles supported on short columns, which encase pipes draining the soil above. The roof holds the South Lawn, with large trees planted in the deep dishes of the concrete forms.

The car park was proposed in Bryce Mortlock's 1970 Campus Master Plan to meet rising parking demand while keeping the core campus landscape. Loder and Bayley, with Harris, Lange and Partners, prepared the designs under engineer Jan van der Molen. Eighteen appeals went to the Building Regulations Committee before approval. Work ran from May 1971 to November 1972, and the structure joined the Victorian Heritage Register on 6 April 1994.

The east entrance incorporates a door from a 1745 house in St Stephen's Green, Dublin. The west entrance is built with a salvaged doorway framed by two Atlas figures from the demolished Colonial Bank offices on Elizabeth Street. These fragments give the car park entrances a character unlike a typical parking structure.

The garage sits beneath the South Lawn, with its east entrance off the lawn near the Old Quad and its west entrance facing the Baillieu Library and John Medley Building. The roof is a planted lawn crossed by paths, so pedestrians pass over the structure rather than through it. The interior is a working car park, so enter on foot with care and watch for vehicles and low clearance.

The car park's roof is the South Lawn itself: the concrete dishes are deep enough to hold soil for large trees, and the columns encase pipes that drain the planting above. Miles Lewis called the structure the most important non-residential design in the country at the time. It later served as the police garage in the first Mad Max film.
