We set out to create an ultra-high performance, attainable, less-is-more home that can be recreated in various ways for future clients’ needs. This one is framed entirely with steel and clad in a curtain wall originally designed for refrigerated warehouses. The living space occupies a compact, 30X30 footprint, yet it offers a 2,700-square-foot open floor plan. It’s an efficient yet generous design suitable for sites as diverse as a mountainside or infill lot. We repurposed as many materials as we could during its construction. Barnwood serves double duty as both a subfloor and finished ceiling. Old growth framing materials from the condemned house that previously occupied the lot were given new life as stair treads and handrails. Acrylic panels sourced from Craigslist now let ambient light onto stair landings.
