位於聖盧西亞保護區綿延起伏的山丘上的“毛毛蟲”住宅的設計旨在突出住宅與這片土地的聯繫。客戶曾經住在由Cliff May設計的房子中，因而對現代“草原房屋”這個住宅類型情有獨鍾。客戶希望在這個基地上建造一個牧場房屋，同時尊重現有的自然環境。“毛毛蟲”住宅得名於其形似毛毛蟲的平面造型。住宅使用了環保的設計元素且對於草原住宅的當代形式進行了探索：它有著橫向延伸而豎向較低的體量，緊密連接室內室外空間的開放式平面，以及圍繞著廚房鬆散排布的客廳。
The design for the Caterpillar House, sited on the softly rolling hills of the Santa Lucia Preserve, sought to accentuate a connection to the land. Having lived in a Cliff May home, the client came to the project with a love of modern ranch houses and looking for an environmentally-conscious response to a beautiful site. The Caterpillar House implements sustainable elements while exploring a contemporary version of the ranch ideals: 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.

房屋和基地在形態和內涵兩層意向上都被連接起來。挖掘出來的泥土用於建造夯土牆。這些夯土牆微微地彎曲，回應著基地的地勢，同時也作為一個蓄熱體，日夜調節著溫度。靠近家中的三個水箱存儲雨水並提供所有物業的灌溉需求。大型朝南的玻璃門打開後，主要起居區和大型的現代門廊以及帶遮陽篷的戶外露臺就從空間上連接在了一起。該遮陽篷可以調節大小，這樣娛樂區域的大小可變得更加靈活，滿足客戶不同的需求。窗戶，自然通風和可調節的遮陽簾組成了住宅的被動加熱和冷卻系統。另外融入設計之中的光伏板產生房屋所有的能源需求，同時又不會破壞與山丘相呼應的優美的屋頂曲線。
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. 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 sun shades 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.

“毛毛蟲”住宅是加利佛利亞中部第一個獲得 LEED白金認證的住宅。
The Caterpillar House was the first LEED Platinum Custom Home on California’s Central Coast.
