We are a general contractor based in the greater Seattle area specializing in remodels and new home construction. We can transform your existing structure into the house of your dreams, build you a backyard cottage, or start from scratch to build you an entire new home. We do second-story additions, basement expansions, house lifting, and structural work. We can help you get the primary bedroom, bathroom, or kitchen that you've always wanted, and can make sure that your addition blends seamlessly with your existing structure. We can get you set up with architects and engineers to get your project started, and our team of professionals will get your project finished. We guide you through from start to finish: from demolition, framing, plumbing, electrical, drywall, and flooring all the way to finish carpentry, tile work, built-in cabinetry, and fine finishes.

"We had a great experience working with NRC Homes on a significant remodel as we prepared to move into our new home. They were highly organized, very communicative, and a pleasure to work with. Despite a tight timeline and several changes along the way (Due to changes from us), they delivered everything on time and were incredibly patient and flexible. We’re so grateful for their professionalism and would absolutely recommend them!"

"Anyvision and Chase were excellent! Their bid was competitive, and their contract was clear and straightforward. What began as a simple shower pan repair turned into a full master bath remodel and a new roof due to water damage. Having dealt with poor contractors for 45 years, we feared the worst, but Chase handled everything seamlessly. He assessed the damage, adjusted the plan, and had the skilled crew to execute both repairs and high-quality finishes. The team was punctual, professional, and kept our home clean. Chase’s tile specialists did exceptional work—no metal edges, just beautifully mitered finishes. With the remodel being unexpected, we had to make quick decisions, but Anyvision’s designer and CAD renderings helped us visualize everything. Chase was onsite daily, keeping us informed with updates, photos, and videos. Challenges arose, but Chase managed them like a pro—offering smart design input, controlling costs, and maintaining quality. This was the best contractor experience we’ve had in the PNW. Anyvision is the real deal, and we’d hire them again in a heartbeat. Their communication, expertise, and customer-first approach set them apart"

FAQs for addition to existing structure building service projects in Seattle, WA

You can typically raise your roof by four to eight feet, depending on your home's structure and roof design. The exact amount depends on factors like roof slope and framing support. Raising the roof creates additional interior space, enhances natural light, and increases your home's value. Consult a professional to determine the feasible height increase for your home.

Yes, you need a building permit to raise your roof. Obtaining a building permit ensures your project complies with local building codes and safety regulations. A professional contractor can assist with the permit and inspection process and ensure all legal and safety requirements are met. Your contractor will be familiar with building codes in your area, which can differ between cities or states.

While it's possible to raise a flat roof, it requires extensive structural modifications. Flat roofs lack the attic space and support structures of pitched roofs, so raising them involves significant engineering to ensure safety and durability. This process can be complex and costly, so professional assessment is essential before undertaking a project of this magnitude.
