The clients have lived in a family Queenslander in Toowoomba for a couple of decades, where they have raised their now grown up children. Our brief was to design a compact 150 SQM single level house on their new 281 SQM suburban site located in the heritage Mort Estate area – a classic downsizing scenario. The clients were initially interested in building over two levels, however the heritage department were not in favour of this. They required a low maintenance new house that uses minimal energy to run. To that end an array of sustainable features has been included. Creating a contemporary piece of architecture that responds appropriately to its varied heritage and industrial context was a fundamental challenge.
