“This is a really lovely backyard ADU,” a jury member said. “I like how it’s sited and what they did with the roof to create a wonderful space for music” on the mezzanine. After renovating the client’s Midcentury Modern house during the pandemic, the architects were called back to design a work-from-home studio in the backyard. “The house has a lot of covered porches; we wanted to re-vision that experience in the studio,” says Chris Brown, AIA. The upstairs portion cantilevers over the front door, and the building’s window placements “create an almost prismatic geometry,” Chris says. A north window points into the tree canopy, while a lower south window faces the family play structure. “You can see through the building south to north, creating a periscope for viewing the tree canopy.”

Its 1×4 vertical cedar siding matches that of the house but is stained instead of painted to expose the mottled grain; and the board-formed concrete foundation echoes the terraced site walls. Interior materials are durable but richly detailed: hand-troweled concrete floor, white oak cabinetry and stair, and a steel handrail. “We chose beautiful materials but tried to deploy them in a way that didn’t feel as precious as the way they’re used in the house,” Chris says. The judges noticed, praising the “good details.”
