Interurban Stacks

Location: Tukwila, Washington

Status: Design

Services: Architecture, Site Planning, Interior Design

Project Type: New Construction Apartments over Retail


Located in the City of Tukwila, this 4 stacked units sits over a ground level commercial Retail.  The site posed a major challenge. Majority of the site is on a critical area steep slope. Zoning of the site required ground level retail and limited density to 4 total units. 

The design draws inspiration from the site's transitional context—positioned between an industrial zones, medium-density residential areas and lush forested green space. A material palette of metal and wood was selected to reflect this unique setting, balancing durability with warmth to establish a strong sense of place.
