A new 3-story house on a small corner lot in the city. 1900 square feet with 3 bedrooms and 2-1/2 bathrooms. The great room and its balcony deck are on the top floor to enjoy views of both downtown Seattle and Mt. Rainier. Locating the front porch at the middle floor makes the entry more inviting.

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.

Cle Elum Cabin

VELOCIPEDE architects designed this cabin for a professional couple and their two young sons as a weekend retreat – a place to unwind from their hectic life in the city and focus on family.  Thoughtfully perched on a steep hillside overlooking a small valley outside the town Cle Elum, Washington, this budget-conscious 1,400 square foot cabin has three-bedrooms, two-baths and a bonus loft/play area.  The main living/dining room is a double-height volume capped with an exposed wood ceiling supported by wood beams, all sustainably harvested FSC lumber. The property is in a Fire-Wise community, requiring all exterior finishes to be carefully chosen for fire resistance and surrounding vegetation to be cleared.  High on the owners’ wish list were a connection to nature, a large deck for entertaining, and a place for the children to take off their muddy shoes after romping in the woods.

Fine Homebuilding HOUSES 2019 Best Energy Smart Home award winner (click for article)

New Passive House on a hilltop in Carnation, WA.  Three bedrooms, two baths with an attached four-car garage.  The aesthetics were inspired by rural barns which created an efficient building form to achieve the Passive House standard. This project was built by the homeowners themselves over the course of five years.

Net positive energy is achieved through super insulation, triple glazed windows, rigorous air sealing, a Heat Recovery Ventilator,  solar hot water, and PV panels.  The 8,800 gallon tank collects rain water from the roof to supply 100% of potable uses inside the house, the first house in King County (greater Seattle) to do so. Low toxicity materials were used throughout the building, most lumber is certified FSC, and the building is a Certified Passivhaus by PHIUS+.
