The Project was an opportunity to utilize high performance and sustainable building strategies to guide the design of a regionally Modern house. Our intention was to minimize disturbance to the site, insert a building that engaged and responded to the textures and palette of the site, and by introducing a terraced solution, blur the divisions between 'house' and 'landscape.
The south facing sloped site was anchored by an existing logging road, which when upgraded to driveway, became a level datum anchoring the northern exposure of the house and pool, and will guide placement of a future studio and garage building. In this way, the house and pool take full advantage of southern exposure /passive gain and near and distant views.
The house, as a family retreat, accommodates three distinct bedroom suites, one on each of the three finished levels, clustered west of the terraced common spaces of the kitchen, dining area, and living room.
By internalizing and externalizing primary structure (steel and concrete), we eliminated thermal bridging, and applied a structural solution to bring scale, texture and detail to the range of interior spaces. This approach reduced exterior walls to pure enclosure, implementing wall and roof SIPS panels for maximum thermal performance. Differentiated use of concrete and stone are guided by this approach. With a retaining wall assembly sandwiching 3” of XPS foam with interior textured/smooth concrete and exterior stacked stone veneer above grade , we were able to introduce interior texture and exterior durability to this retaining wall assembly. The balance of the exterior cladding consists of local combed/band sawn pine and zinc sloped roof cladding.
The thin profile of the sloped roof elements are another product of this approach. By designing self-supporting roofing (cantilevered steel plate soffit panels), we eliminated the necessity for structure penetrating the building enclosure creating an singularly ultra- thin roof form.
