Completed alongside the Maple Leaf Residence, this detached accessory dwelling unit sits at the rear of the property with its own alley access and parking below, forming the second of two connected homes on a single urban lot. Rooted in Washington State's middle housing provisions, which require cities across the state to expand zoning for denser housing types, the unit was designed as a complete home rather than a scaled-down secondary suite. An open main level places a full kitchen and marble waterfall island alongside a living area anchored by a linear fireplace and warm wood paneling, with bedrooms, a dedicated office, and full baths arranged above. For La Union Studio, the DADU shows how added density can serve real household needs rental income, multigenerational living, or guest accommodation without compromising the quality of either home.
