Benjamin Benschneider A Seattle family was expecting their third child and hoping to find space for an additional bedroom within their existing one-story home. A small second floor addition was considered but the cost and disruption to the family living space presented serious drawbacks. A new detached garage and DADU (Detached Accessory Dwelling Unit), to be located in the backyard, was proposed to free up the existing basement garage for the new bedroom. The new building is modest and simple, designed with a scale and character to complement the existing house and neighborhood.
