detached accessory dwelling unit - seattle, washington

Under construction Summer 2021. Our client enlisted our help to design a modern, boxy accessory dwelling unit in their backyard, which abuts an alley. A unique challenge was the fact that the backyard sat upon a stone rockery approximately 10 feet above the alley. This ADU with garage was tucked into the hillside using it’s own foundation walls to replace the rockery. ADU access is from the backyard, while the garage became level with the alley. Contemporary was the name of the game here, with a flat roof housing a rooftop deck, a sleek canopy wrapping around to protect entrances from weather, and an overall feel of building block rectangles. A mixture of thin, horizontal siding and large panels in contrasting tones finishes the exterior. The 1,280 sf interior contains two bedroom suites and a cozy great room.
