To disappear to a remote house off grid requires both technology and tenacity. First there’s energy use and battery storage to consider, adequate rainwater collection and, of course, bushfire planning and design. For practice director, Simon Anderson, eight acres of native bushland in the Blue Mountains proved an irresistible temptation for research and development. Testing a skillful combination of passive and environmentally sustainable design methods on his own 8-star bush block house has helped Simon to minimise his family’s energy. Importantly, the project also served as a significant early prototype for the practice’s mounting expertise in off grid house design.
