This is House Ocho, a project in Carmel, California, designed by Feldman Architecture. The home is beautiful and modern with striking clean lines, though perhaps its most prominent detail is a lively green roof that hides the structure in the hillside of a nature preserve in the Santa Lucia Mountains.

With seismic activity in the area, generous windows and views, and other site constraints, House Ocho needed a design to minimize roof loads. With the help of Paul Kephart, the expert behind iconic green roof projects such as California Academy of Sciences and the Vancouver Convention Center, this green roof was designed with six inches of lightweight soil and a water retention layer that maintains soil moisture using small cups.

For plants, the roof blooms with wildflowers such as tidy tips, lupine, poppies, and goldfields, as well as strawberries and perennial plants such as Sand Sedge, Point Joe Fescue, and yarrow. Jonathan Feldman detailed other more technical aspects of the living roof in an article for Green Architecture Notes.

House Ocho has 2,900 square feet and a small cottage for guests. Additional green aspects include the integrated photovoltaic skylights, custom windows to optimize passive solar heating, thermal mass in the form of concrete floors, radiant heat floors, recycled denim insulation, and sustainably harvested wood floors.

House Ocho was built in 2004 by Groza Construction with the assistance of Fulcrum Engineering, Loretta Gargan Landscape + Design, Blasen Landscape Architecture, lighting designer Steinbeck Technical Consulting, and green roof consultant Rana Creek.
