Sited on the softly rolling hills of the Santa Lucia Preserve, the Caterpillar House implements sustainable elements while exploring a contemporary version of the ranch ideals.
Connecting the home literally and figuratively to the site, excavated earth was repurposed for the construction of the walls. These rammed earth walls gently curve in response to the site’s contours and also act as a thermal mass, regulating temperatures from day to night.
Massing that is low and horizontal, an open plan with a strong connection between indoor and outdoor spaces, and main living areas that center informally on the kitchen.
Three tanks close to the home proudly store rainwater and provide all of the property’s irrigation needs. Large south-facing glass doors open the main living area to a large covered contemporary porch and to an outdoor patio with sunshades that expand and contract to allow for a flexible entertaining area that responds to the client’s needs. The glazing, natural ventilation and operable shading also act as a passive heating and cooling system. Integrated photovoltaic panels enable the house to produce all of its own energy requirements without compromising the graceful curve of the low roof against the hill.
