Grangewood Autonomous House Richard and Elaine Thomas needed a house from which to manage their woodland and wild boar farm. A post and beam building, the house is one and a half storeys and a simple rectangle on plan. The house is off-grid with an electrical supply of a wind turbine, photo-voltaic panels and back up generator. To this was added a solar panel for hot water and the wood stove for cooking, space and water heating. A design and build project using Quercus allowed the clients hands on experience in building their house.
