Local context
Why Homeowners in Mercer Island Choose This Service
Remodels in Mercer Island usually start with the stair that is already there. With midcentury homes and large custom remodels common here, we plan layouts and materials that suit the existing architecture rather than forcing a one-size design.
Mercer Island is mostly single-family homes, many midcentury, along with larger remodels and new builds.
We serve neighborhoods such as First Hill, East Seattle, Mercerwood, about 6 miles from Seattle.
