Robert Albano’s ADU: 2 Units for Aging-In-Place

Accessibility, sociability, rentability, and sustainability were driving factors for their design. The focus of the design was aging-in-place for both dwellings. A secondary goal was energy-efficiency so that the dwellings would be less expensive to heat and cool. They insulated the units with R-40 walls and an R-60 roof. Tight air sealing was also important and they ultimately achieved 2.2 Air Changes per Hour (ACH).

Stephen Williams’ ADU: An ADU on the Alley

Stephen has always enjoyed the challenge of making a small space functional and comfortable. He had already built two ADUs, so it made sense that he would build an ADU on his own property when the opportunity arose. In 1998, Stephen purchased a lot in the Foster-Powell neighborhood with an existing house, which had been condemned. He remodeled the 1908 home and rented it out. He then designed an ADU for the back half of the lot, abutting the alley.

Susan Moray’s ADU: Updating History in Ladd’s

As she worked with Jack, Susan’s primary design consideration became maximizing the size of the ADU while adhering to Historic Neighborhood requirements. Prior to applying for her permits, Susan paid for a design consultation meeting with the city of Portland and Jack brought preliminary sketches to explore various possibilities.

My architect, Jack, did his homework on what could be built, given these limitations and nailed down a design that was accepted on the first try with no changes. That was impressive. We were told by everyone we would never get what he wanted past city permit without going through design review but he did. -Susan Moray
