The home boasts 3 bedrooms, 3.5 bathrooms, open-plan living areas, a music room and a screened porch that includes an outdoor fireplace.

  • Split system air-to-air ducted heat pumps for space heating.
  • Indoor air-to-air heat pump for domestic hot water.
  • Independently ducted European energy recovery ventilator for high-efficiency, continuous mechanical ventilation.
  • Shou Sugi Ban charred wood siding has low embodied carbon, requires little maintenance, and is very durable.
  • Insulation products selected to minimize home’s carbon footprint and to significantly exceed building code requirements.
  • Dense-pack cellulose insulation installed in 12” double walls that virtually eliminate thermal bridging.
  • Dense-pack cellulose insulation installed in 20” rafter trusses that virtually eliminate thermal bridging.
  • OSB wall and roof sheathing with integrated WRB and taped joints for exceptional air sealing.
  • Both exterior walls and roof are fully vented outboard of the air-tight sheathing to prevent moisture accumulation and damage and reduce maintenance.
