Built by a crew of three, the home makes a virtue out of being unfussy and straightforward. The north-facing glass wall under the gable, with a triple-glazed facade, doesn't require shading or insulation. The quick-to-build structure—which consists of just structural insulated panels (SIB) made from OSB panels with a foam core, and a concrete floor that retains heat—doesn't include any complicated systems or require much maintenance.
