In response to environmental concerns, glazing is thermal, double-paned glass with a low-e reflective coating. The extensive glazing promotes passive solar heating and provides abundant natural light. Exposed concrete floors, with energy-efficient hydronic heating, also serve as a heat sink for passive solar heating. Sun screens and operable windows providing cross-ventilation provide for natural cooling, alleviating the need for mechanical air-conditioning.
The clients wished to completely reorganize and expand the existing cabin's layout. Given the site development restrictions, the design concept evolved into making a small addition replacing a portion of an existing exterior deck. The addition was conceived as a wood box "insertion" into the volume of the main cabin structure. The new box "slides" in over the existing floor structure and cantilevers out over existing foundation walls, thus not affecting the existing drain field. This wood box contains the master bedroom, bath and kitchen. The exterior shape and wood finish of the box extends from outside to inside emphasizing the continuity of the form. Clerestory windows separate the box "insertion" from the main structure's shed roof above. The daylight basement was remodeled to include a family room, two bedrooms, a new bath, and a laundry and mechanical room.
The cabin structure is sheathed in horizontal and vertical Ipe wood siding; the foundation below is sheathed with fiber cement panels.
