Looking back while archiving some past projects, I came across this one. This highly sustainable home was designed and built more than 15 years ago. It was the first house to receive planning permission in Dalby Forest in over 50 years, approved for its architectural merit and sustainable design. I absolutely loved working on it—and with the clients, who were part of my life for more than three years. The photos below were taken in 2016, during my last visit.
