From infrastructures built by the indigenous tribes to buildings made by local tradesmen, the idea of sustainability is always seen as responding closely to its climatic conditions, as well as cultural backgrounds. In Australia the extremities in living conditions across the continent provide grounds for distinctive architectural undertakings. Together with Wendy Lewin, Maryam Gusheh, and Tom Heneghan, ‘a+u’ presents an overview of the notion of sustainability in the Australian context through a rich diversity in topology and styles of architecture, including projects by Glenn Murcutt, John Wardle, Officer Woods Architects, Andrew Burns, Troppo Architects, and others.
