Bluff House sits along the crown of a 30-mile long oval bluff range, its intersecting volumes growing out of the site’s gently sloping terrain. Approaching the house from the former logging road carving through the site’s rhythmic woodland, the building’s silhouette slowly emerges from the dense vegetation. With its simple, diagrammatic geometry and layered use of materials, the house achieves a legible clarity and rustic warmth that welcomes visitors.
CONTEXT:
Informed by early studies of the geology of the region, the house’s two concrete organizing walls prove as strong and distinct as the metamorphic quartzite composition of the bluffs that have resisted erosion from weathering, rivers and glaciers over the past 350 million years. Growing out of the staggered solid walls are lighter assemblies of solid cedar sided panels and glazing. The fenestration patterns offer a variety of vistas from, and often through, the house echoing the varied site lines one experiences when walking through the forested bluff. The windows alternate between full height vertical apertures and horizontal clerestories, but always follow the strict 59” structural grid of the building’s exposed structure.
ORGANIZATION:
The first concrete wall separates residents entering through the garage and guests entering through the solid wood entry door. The separate entry sequences are rejoined at the entry foyer where the concrete mass extends into the interior space. Once inside, a circulation gallery invites you into the main living hall, or alternately down to the mechanical and storage walk-out level. The open plan of the public volume includes kitchen, dining and living space and opens up to extended views of the forested bluff the house literally and figuratively grows out of.
TECHNICAL:
The building’s envelope is composed of super insulated polyurethane SIP wall and roof panels and high performing low-e coated argon filled glazing. The 1,490 sf of finished main level is heated with a hydronic radiant heat system that uses the mass of the lower level slab to maintain a comfortable environment. The heat stored in the slab naturally radiates up through slots, directing warm air past the main level glazing and is returned through the open stair, completing the convection cycle. Outside air is filtered through a heat recovery ventilator, bringing fresh air into the home without sacrificing thermal performance.
