Located in the Fremont neighborhood of Seattle, this narrow, three story house has a magnificent view to the Olympic mountains. The project added a two story Mother in Law (ADU) addition for a second family to rent. In between, a new skylit entry hall features a pond fed by rainwater from the addition roof.
Though similar in appearance to the main house, the ADU incorporates more progressive construction techniques than its 20-year-old parent. ICF stem walls bear on footings of concrete mixed with 43% flyash. Walls and roof structure are SIP insulated sandwich panels, and cement board siding is installed over a rain screen.
Heat is provided by a hydronic radiant slab below and a single fan coil unit above. The roof gutters gather water in reused wine barrels for irrigating the yard. The existing garage became a demonstration site for Seattle's eco-roof initiative. Certified Built Green 3 Star.
