Home addition construction in Seattle, WA

Yes, we handle structural framing and detailed finish carpentry and millwork as part of the same project. This keeps your addition coordinated from the foundation up through the final trim details.

We serve homeowners across Seattle, Bellevue, Kirkland, Redmond, Mercer Island, Sammamish, Issaquah, and several other communities in the region. If you are located in one of our service areas, we are glad to discuss your project.

We build ground-level room additions, second-story additions, and bump-out expansions for homeowners throughout the Seattle area. The right approach depends on your lot, your zoning, and what you want the new space to do.

The owners are personally involved throughout the project, not just at the start. We manage the planning, coordinate the work, and stay in direct communication with you from beginning to end.

Older homes can absolutely support additions, though they sometimes require structural review before design is finalized. Our team has hands-on experience working with existing residential structures across the region, including older homes in Kirkland and surrounding communities.

Home additions in Seattle require construction permits through the Seattle Department of Construction and Inspections, covering plan review, structural verification, and inspections. We plan ahead for this process so it is accounted for from the start of your project.
