The client brief was to create a solar passively designed home, where the clients could age in place and have direct access to the garden. Also to generate sufficient renewable energy for daily use and capture rainwater from all hard surfaces for internal and garden use. They wanted a small home, offering a smaller footprint resulting in 146m2. The benefits of solar passive design is to heat the home passively from entry of the winter sun, whilst shading the north windows in summer. A north facing deck leads off the living/dining and then onto the food production garden, which is watered by rainwater captured from the roof. The materials used in the house include Weathertex Ecogroove which is 97% wood fibre pulp and 3% wax, to avoid it being tasty for termites. Recycled solid red bricks have been used in the living area for a thermal mass wall. The house has been zoned for different uses and separated with doors. Wet areas are kept together to reduce the water runs.
