The house has a compact floor area and relies on passive solar design. In essence the design is extremely simple. The house has highly insulated north, east and west walls with the minimum number of openings compatible with acceptable daylight levels. The southern elevation consists of a fully glazed two-layer sun space. The sun space will contribute to cooling by the admittance of pre-cooled air in the summer from below ground and by minimising the effects of solar gain through enhanced ventilation utilising a stack effect, including creating a low-pressure zone above the mechanically opening vents below ridge level.
