Wallingford Passive House

Wallingford Passive House, a new Seattle home designed by Whitney Architecture and built by Hammer & Hand, brings the comfort and efficiency of passive building to an urban infill lot in Seattle’s Wallingford neighborhood. The clients – one an engineering professor, the other a statistician at a tech company – are soon-to-be empty nesters who embarked on the project to create a home for aging-in-place close to shops, parks, and other neighborhood amenities.

The narrowness of the lot dictates a vertical form for the 3-bedroom house. To provide for future accessibility, the design by Whitney Architecture incorporates an thermally-isolated elevator inside the envelope, a unique feature among single-family Passive House projects. The home also has a ramp to the front entry.

Hammer & Hand’s construction of the home incorporates materials salvaged from the site’s original structure, a modest home in disrepair. Upturned roof “wings” and modern building materials define the new home’s contemporary aesthetic.

We achieved an airtightness level of 0.315 ACH50 for this home – passing the Passive House requirements with flying colors. Learn more in this blog.
