Site conditions: previously developed land, running water, preexisting structure(s)
Materials and Design Strategy
Materials: We wanted to fix an existing building on a developed site rather than build new, even with the attendant compromises. Windows, doors, fiberglass batts, and mechanicals were salvaged for others’ use. Exterior trim is river-recovered cypress. Wood floors are salvaged oak.
Special architectural measures: Superinsulation, 50% of the glazing located on the south facade, high solar transmission glazing
Indoor Environment Description: Energy recovery ventilator exhausts the bathrooms and supplies fresh air to the bedrooms
