The house is organized around a Z-shaped central gathering space bounded by private bedrooms. The envelope conforms to an economical two-foot grid module limiting construction waste, reducing labor and resulting in a low-cost project with high-design spaces. The grid restrained the building footprint, became the guide to navigate site constraints and provides a framework for moments of exuberance. Clad in a prefinished steel siding with cedar accents, the house is an affordable solution in an otherwise expensive building market. Super-insulated walls have no thermal bridging and the SIP roof (with its exposed underbelly) results in a home with fractional cooling and heating costs.
