Constrained by zoning code, this project was only able to add 119 square feet of new footprint. So the homeowners gave a third of their existing family room to create a new Accessory Dwelling Unit for grandma to occupy. Connected by an interior door to the main house, but with its own exterior door for independent entry, the ADU allows the family to easily get together or remain separate as needed. This project in the schematic design phase.
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.
New custom home, 4 bedroom, 3 bath, with 2 bedroom, 1 bath mother-in-law suite and 2-car detached garage.
The new house overlooks a half acre vegetable garden and fruit orchard which the owners tend. The view beyond is to a lake and mountains from all the principal rooms of the house.
Certified LEED for Homes Platinum and Built Green Emerald Star, with 17kW photovoltaic array, solar hot water vacuum tubes, and 12,000 gallon potable rainwater collection system.

The Building of the Eastside Harvest House
The owners came to VELOCIPEDE to design a Detached Accessory Dwelling Unit (DADU) in the back yard of their single family home. For privacy, they requested maximum separation from both their existing house and the new townhouses across the alley. The unit is 800 square-feet - the maximum allowable by code - and features an open master suite on the upper level that leads to two roof decks. At ground level are the living/dining/kitchen, laundry, guest room, and powder room. Exterior materials harmonize with those of the main Craftsman house.
