Huff / Craven Net Zero House


Design for a new net-zero-energy house including an airtight and superinsulated enclosure, heat recovery ventilation, and photovoltaic array.  Exposed beams in double height living room ceiling. Detached Accessory Dwelling Unit (DADU) wrapped in weathering steel with spiral stair inside.  Completed in summer 2018. 

Tangletown DADU


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.

Juneau Street short plat

Short plat to create four single family lots in Seattle.  Each lot has a 2-bedroom, 1-bath house over a full basement, a 1-bedroom, 1-bath Detached Accessory Dwelling Unit, and two surface parking stalls. 

The site had never been built, in part because it contained a steep slope and in part because it had no street frontage.  We connected two adjacent streets with a one-way driveway to provide vehicle and fire truck access.  The site layout groups the new buildings into two clusters to enlarge the apparent size of the private open spaces. 

The project received a master use permit, but was abandoned by the owner at the depth of the Great Recession.
