Expert Accessory building construction in Seattle, WA

Accessory building construction gives Seattle homeowners a way to add dedicated space without expanding the main house. Framework Construction handles the full build process, from structural framing to finish carpentry, for detached garages, backyard workshops, art studios, home offices, and guest structures. Seattle lots vary widely in size, slope, and setback constraints, and each project requires careful planning to work within those site conditions. Our co-owner Peter brings over 30 years of hands-on construction experience, and together our team has worked across structural framing, finish carpentry, roofing, siding, and more. That range of experience matters on accessory builds, where the structure needs to be framed correctly, weatherproofed properly, and finished to match or complement the main home. We are a family-owned company, and we stay personally involved from the first conversation through the final walkthrough. We serve homeowners across Seattle, Bellevue, Kirkland, Redmond, Issaquah, Sammamish, Mercer Island, Woodinville, Bothell, Kenmore, Bainbridge Island, Clyde Hill, Gig Harbor, Maple Valley, Fox Island, and Poulsbo. If you are ready to add a functional structure to your property, contact Framework Construction to get started.
