The form of this house in the hills of Berkeley evolved between competing topographies and the micro-climate. While often sunny, the air is dry and chilly. The main living spaces of the house are designed to warm up quickly in the sun, and cool off quickly with cross ventilation and ceiling fans. The spaces are therefore almost always open to the outside air, and feel like covered porches rather than interior rooms. The glazed walls also provide specular views out to the San Fransisco bay.
