Located on the peninsula south of San Francisco, this house sits on an internal suburban flag lot. It was build in 1950s but recently remodeled. A cool manmade pond that was there before become the thing that add a feeling of being at a vacation retreat to every day life. The site consist of four buildings – the main house, study, pool house anda garage. All of them are focused on the pond, garden and pool. There is also a terrace near the pond that is separated from the interior by glazed sliding doors. The roofs conceal photovoltaic and solar hot water panels. The house is heated with a radiant system in the stone floors, and despite the hot climate it is not air conditioned, but passively cooled with a combination of overhangs, shades, and operable windows. It also features many green building materials, including high fly-ash concrete, formaldehyde-free casework and denim insulation. [Turnbull Griffin Haesloop Architects]
