Caner/Beier Residence

Location: Napa County, California, USA

House area: 2,680 square feet/249 square metres

Site area: 20 acres/8 hectares

Description: Sited on a north-south axis, to fit into the hillside and opening up to the western view, the great room presented a passive solar challenge. The doors to the west are shaded by a deep verandah, the roof of which bounces light through the high windows to illuminate the ceiling. By holding down the roof of the kitchen, a high south-facing window allows light deep into the space. A dormer is added in the kitchen for both daylight and relief from the low ceiling.

The main spaces are of sprayed earth construction. Taking advantage of diurnal temperature fluctuations, the 18-inch thick (46-centimeter) earthen walls provide both thermal moderation as well as a rich, patinaed finish. Rammed earth is used at the fireplace and verandah columns for drama. A modern version of an ancient building system, the earthen walls give the structure a timeless quality. The thick walls are topped with a roof structure of recycled fir trusses and cypress decking salvaged from pickle barrels.

Stained concrete floors and the natural walls are balanced by a rich collection of salvaged materials, such as a recycled glass countertop and a piece of a bowling alley, chosen for their durability as well for their sustainability.
