Gibson's November 1974 Cultural Centre master plan differed significantly from his winning competition design for the Gallery and gave Gibson the opportunity to further demonstrate his planning principles for inner city development. Stanley Street was to be diverted under the Victoria Bridge through to Peel Street, with the Art Gallery and Museum occupying one large block. The scheme included building forms with oblique angles to the street grid, to address the main approaches. The Performing Arts building, comprising a single, multi-purpose hall, and the Art Gallery, extending from the Museum to the river's edge, were aligned diagonally around a Melbourne Street axis to address the approach from the Victoria Bridge. Pedestrian bridges provided access across the site over Melbourne Street and to the South Brisbane Railway Station over Grey Street.
