midcentury renovation — SEATTLE ADU — PACIFIC NORTHWEST DESIGN

SEATTLE, WASHINGTON

Originally built in the mid-1950s, this extensive renovation pays homage to its midcentury roots. CAST renovated the main single-family home and added a new 780 square foot Accessory Dwelling Unit (ADU) was introduced. The residence now serves as a three-generation family home.

The ADU echoes the massing of the garage, creating a formal courtyard.

The ADU boasts a covered patio that provides private outdoor space. The driveway's configuration was altered to accommodate a garden in front of the ADU, enhancing its privacy and its individual identity.
