Howard and Bernie had an energy-efficient sleepout designed and built that is attached to the existing house by a covered walkway, forming part of a complex of four buildings.
New buildings are solar oriented and follow the four golden rules of good design related to sunlight, open spaces, access and privacy.
The owners have a website SOAP House Design describing benefits of passive solar orientation.
All roofs are skillion and oriented to the north, which shade the buildings in summer and omit the winter sun. They are all 10-degree-pitched, with a cantilever pitch to the north side.
One building is rented from time to time, and three are used by the owners as sleepout, artists studio and house under renovation.
Gold coin donations will go to Benalla Sustainable Futures Group.
