Home Additions in Bay Area | Lutz Custom Builders

Home Additions

An addition has to look like it was always there. We design and build room additions, kitchen and primary-suite expansions, and second-storey additions that match your home's rooflines, siding, and interior finishes. Tying new construction into an older Bay Area house takes care, and after three decades of doing it here we know how these homes are built and where the surprises usually are. You get a clear schedule, a clear budget, and communication at every stage so you always know where the project stands.
