Folded white boxes house living and sleeping spaces while burnt wood (sugi) clad bars enclose bathrooms and storage. Floors are concrete and painted pegboard is used to achieve an illuminated ceiling. All living and sleeping spaces spill to the outside, and secondary indoor circulation provides a short-cut during wet weather. Air conditioning is unnecessary as cooling is achieved by a combination of passive strategies and fan-assisted earth tubes. An off-the-grid guest house allowed the family to live on-site during construction.
