Feldman Architecture’s multiple award winning “Caterpillar House” in the Santa Lucia Preserve, Carmel Valley, California, built by Brian Groza Construction.
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.

The pairing of mass and glass - flood the house with sunlight and store the solar energy in the walls and floors. This strategy can work well in a Mediterranean climate. The Caterpillar House is the first LEED Platinum Custom Home on California's Central Coast.

In an ideal, mild climate with the sun shining brightly, you can throw the doors wide open for several hours during the day and maintain comfortable temperatures within the living spaces. The keys to success are the broad roof overhangs shading the house in the summer, and knowing when it’s time to close the doors.

The Caterpillar House bends along the contour lines of the shallow hill on which it is built. Curved rammed earth walls offer beauty and architectural connection, and add significant complexity to the formwork.

The shallow curves of the house walls repeat themselves in the low patio and planter walls. Capturing rainwater for irrigation, three tanks proudly sit close to the home - a clear sign of the available water resources for landscape.

The glazing, natural ventilation and operable shading act as a passive heating and cooling system, cooling the house in the summer and warming the house in winter. Rammed earth walls provide thermal storage. The window vista also puts the occupants right square in the middle of the Preserve - 270 degree views of the flora and fauna of the Carmel Valley.

Step back and get the big picture of Caterpillar house. To guarantee that all of the pre-fabricated steel roof beams would fit, the roof structure was built before the walls - adding a major challenge for the rammed earth installers.
