Michael Klepinger’s ADU: Ellen’s Garden Cottage

When Ellen’s new university professorship required relocation to Virginia, they had to make big decisions about their SE Portland property. They knew they wanted to ultimately return to their home in Portland and for the time-being they planned to return during academic breaks. It didn’t make sense to leave their beloved home vacant while they were gone. However, if they leased their property they would have no place to call home when they returned to Portland for the holidays. A little ADU solved the problem.

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
