"The Simpson St ADU is a 575-square-foot Accessory Dwelling Unit in the Concordia neighborhood of Portland, Oregon, designed by Polyphon Architecture & Design. The project's unique solution was to place the ADU in front of the primary residence, which was set back far on the property, while still providing ample space for a driveway and access to the main house. The design addresses the narrow building envelope by using a split-level layout. This strategic arrangement allowed the ADU to maximize its internal space while remaining within the side setback requirements. The interior is efficiently organized to include distinct spaces for a bedroom, kitchen, and living area.
