The residence is nestled into a rocky hillside, surrounded by vineyards and oak trees. This location was selected because of the paramount importance of recognizing its potential for enhanced views and for taking advantage of prevailing seasonal breezes. At the beginning of this project there were numerous discussions of appropriate character and design influences. There are many vernacular agricultural structures in this rural region which lent reference cues. Flowing water was another cue, as an irrigation system canal serpentines through these hilly properties, providing water for gardens, yards, and vineyards. The most compelling requirement was for abundant natural light throughout the new home. As the program developed and conceptual designs evolved, several strong themes emerged. A layering effect of building elements allowed the overall mass of the structure to be broken down in scale and proportion. From these concepts, images of a small village of clustered buildings became a theme. By creating a diagonal "slice" through the core of the home and pulling it apart, a skylight galleria was created to flood the interior spaces with natural light. The concept of the interior open-air water courts also allowed shafts of sunlight to penetrate into the central core. The glazed water courts created a wonderful transparency throughout the home.
Sustainability was also at the forefront of the design considerations and their solutions. Recyclable building and finish materials were utilized wherever possible. Materials with a high recycled content were specified. Extensive natural daylighting, through the application of skylights and the careful positioning of windows, ensures almost no need for artificial lighting during the day. The natural ventilation design concepts reduce the power requirement for air circulation and provide a more comfortable indoor environment Natural ventilation was an important consideration in this project's architectural plan. The principle of natural draft and ventilation consists of three factors:
i. Wind pressure on building
ii. Venturi effect
iii. Chimney effect
Since natural energy is used for ventilation, the power requirement for air circulation is reduced. Moreover, by replacing indoor air with cool ambient air through ventilation in the nighttime, heat stored in the building is removed while the cold is stored in the building skeleton, thus enabling a reduction in daytime cooling loads. One of the most satisfying accomplishments of this project was the integration of interior spaces with those outside the home. The structure subtly emerges from the hill with visual interest, and with many surprises as you move throughout the home.
