Set amidst the hills of the Santa Lucia Preserve, the clean linear design of this casual weekend getaway works with the natural landforms to capture views of the mountain range from every room. The minimalist palette of materials —local stone, recycled barn wood, earth-hued plaster walls, zinc and green roofs—feels entirely of the place. Interiors are at once refined yet relaxed, with touches of whimsy. Beds in the cabin-like children’s bunkroom, structurally supported by steel ladders, appear to be floating from the walls. Handmade glazed running bond tile and an enameled stone table in the banquet add light-catching luster to the kitchen. Troweled plaster walls throughout the house are buffed to a soft sheen.
