Magnolia Second-Floor Addition


Location: Seattle
Architect: Vic Opperman

Green Features

  • Heat-recovery ventilator (HRV)
  • Low-toxic materials
  • Careful air-sealing


This major remodel of a 1940 house included a new kitchen and a three-bedroom second-floor addition. Only low-toxic materials were used, and a heat recovery ventilator (HRV) was installed. The house was carefully air sealed and insulated to make it much more energy efficient. New decks on two levels take advantage of the views.
