In April 1973, Robin Gibson and Partners Architects won a two-staged competition to design the new Queensland Art Gallery at South Brisbane, with a sophisticated scheme considered superior in its simplicity and presentation. While this design was never realised, the art gallery that was built as part of the Cultural Centre was in many ways very similar, including the palette of materials and modernist design details inspired by the 1969 Oakland Museum in California. The original design occupied the block bounded by Melbourne, Grey, Stanley and Peel Streets. Over Stanley Street, a pedestrian walkway connected the gallery to the top of an amphitheatre leading to sculpture gardens along the river.
