Adelaide’s education buildings have flexed their design muscle at this year’s South Australian Architecture Awards, run by the Australian Institute of Architects.

The awards are held annually and celebrate excellence and innovation in commercial, residential and public architecture, as voted by architects' peers.

Adelaide Botanic High School by Cox Architecture and DesignInc won three of the highest accolades: the Dr John Mayfield Award for Educational Architecture, the Robert Dickson Award for Interior Architecture and the Derrick Kendrick Award for Sustainable Architecture.

Jurors were impressed with the school’s “superb composition” and integration with the surrounding parklands. One juror called it “a new benchmark for adaptive reuse in South Australia”.

SA chapter president Tony Giannone said the project is “a community asset of lasting value”. “Not just because of its sustainability credentials but also because it provides an example of how this state can provide state-of-the-art educational facilities with outstanding flexibility and adaptability.”

St Mary’s Corner – a new building on the St Mary’s College campus housing the senior school, visual arts faculty and PE facilities – by Grieve Gillett Andersen received the Educational Architecture Award and the City of Adelaide Prize People’s Choice.

The residential categories included more than 21 entries. Architects Ink received the John S Chappel Award for Residential Architecture – Houses (New) – for the second year in a row, this time for Sugar Gum House in Willunga. House and Cart (by Khab Architects) in Wayville also received an award, and Baliol Residence (by Grieve Gillett Andersen) in College Park and Douglas Street Residence (by Ashley Halliday Architecture Interiors) in Millswood both received commendations.

Other award winners include Mitolo Wines by Tectvs, which won the Keith Neighbour Award for Commercial Architecture; the University of South Australia Cancer Research Institute by Swanbury Penglase with BVN, which won the Jack McConnell Award for Public Architecture; and Willunga Mainstreet by Mulloway Studio and Wax Design, which received the Gavin Walkley Award for Urban Design.

The 40 award winners will now progress to the National Architecture Awards to be announced on November 7.
