Vancouver Avenue ADU

ADU · North Portland

The clients had already designed, permitted, and had a foundation poured for an 800 SF ADU. They stopped construction, unsatisfied with the original design. Tweto Architecture worked with the city to completely redesign the ADU while keeping the existing foundation and staying within the original budget.

Contractor: Stephen Hull Construction

The ADU became their home while they rented out the main house. A few years later an opportunity arose to live next door to their daughter, and they built their second ADU together. When they eventually sold the Vancouver home, the ADU proved to be a strong selling point.

The ADU includes a first-floor bedroom and full bathroom. An open loft has space designed as an office but also intended to work as a second bedroom, with a second full bath. The great room opens to a private yard. A small, efficient kitchen tucks to the side. The bedrooms and bathrooms at the west side stack. The upstairs bedroom is configured as a somewhat open loft, maintaining privacy while staying connected and open to the rest of the space. Simple forms complement the 12:12 pitch roof of the historic main house.
