Custom kitchen and bathroom remodels are our forte as we recognize the importance of such spaces within a home. Our team will work closely with you to bring your vision to life. Whether you’re looking to modernize your home or use your current space more efficiently, we’ve got you covered!

Second Stories, Primary Suites, Garage Additions and ADUs
Most of the additions we build on the Eastside fall into a few shapes: a second story over the existing footprint, a primary suite or family room bump-out, a garage addition, a sunroom, or an accessory dwelling unit. Each starts with our engineers, who design the foundation, framing and roof tie-in so the new space matches the house instead of looking bolted on. Your Project Manager files the permit with your city, schedules every inspection, and runs the build to the written schedule in your contract. See completed examples in our home remodeling and additions portfolio, including the Gonzalez home addition in Sammamish and the Zhang remodel and addition in Redmond.
