Conceived as a series of private pavilions interconnected by outdoor and indoor family areas, garden pools and landscaped courtyards, this haven atop a knoll overlooking the Southern California savanna makes its architectural assertions with the thick walls and deep roof overhangs that shield tall windows and ribbons of clerestories from the luminous Santa Ynez Valley sun. The cool, sleek interior with volumes of white walls and green Vermont slate floors give out on all sides to views of 400 gently rolling acres of grapevines, cattle grazing country and the mountains beyond. 6 bedrooms, 6 full baths; garages for 4 cars; separate managers residence and four-stall breezeway barn.
