The proposed house aims to celebrate the site’s expansive views and remarkable terrain through the form of a simple, rectilinear, wood and concrete volume. Anchored on the lone flat area onsite, the house’s orderly, concrete framework accommodates a large family and creates a perch from which to take in the vistas of the secluded property and beyond. The slim volume is optimized for the Sonoma climate through its design and placement on site. Its proportions maximize the interface between the exterior and interior, allowing for natural light, ventilation, and direct access to outside from almost every room in the house. While this exposure to the outdoors is practical during much of the year, it is also critical to passively protect against the intensity of the summer sun. A second story loggia wraps the east, south, and west facades to provide a robust buffer from the extended solar exposure of the summer months. The loggia’s deep overhangs create shaded zones around the perimeter of the house from which to appreciate the views at grade and the upper deck. Proposed building materials have been chosen for their organic, rustic appearance and tactile qualities. And, in light of the recent fires, the Owners wanted to focus on non-combustible construction for their new home. A board-formed, grey concrete framework establishes the structure and rhythm of the house. Solid walls infill the open framework, defining separate spaces on the interior of the house. Concrete shear walls will infill the expanses between columns at the building envelope. The exterior faces of these solid walls will be clad with unsealed wood siding, which will weather naturally, greying and receding into the landscape progressively more over time. The primary interior spaces will be clad in wood to add warmth and evoke the traditional building materials native to the region. With its elemental materiality and efficient, thoughtful configuration, the proposed dwelling would be a contextually-rooted, environmentally-responsive addition to the site.
