From our very first appointment with Gershon, we felt confident we were in excellent hands. He listened carefully to what we wanted, offered thoughtful design suggestions, and walked us through the process and timeline in a clear, transparent way. Every step—from initial design and planning to the finishing touches—was handled smoothly, with consistent updates so we always knew what was happening next. The crew that worked on our home was hard working, professional, and very knowledgeable. They arrived on time, respected our home, and kept the work area as tidy as possible, which we really appreciated. The finished kitchen looks fantastic and functions even better than we hoped and the quality of the workmanship really stands out. Friends and family have already commented on how beautiful and well thought-out the space is. We would not hesitate to hire GS Design & Build again for future projects. If you’re looking for a top-tier contractor for your home remodeling, GS Design & Build are an outstanding choice.

Expert ADU Construction in Los Gatos, CA
ADU construction in Menlo Park gives homeowners a real way to add livable space without buying a new property. At GS Design and Build, we handle the full process — from site evaluation and design through construction and final inspection. Menlo Park allows ADUs on single-family and multifamily lots, with no minimum lot size required and a state-mandated 4-foot side and rear setback. Units can be detached, attached, or converted from existing space like a garage. Across San Mateo County, nearly half of all new housing units permitted in 2024 were ADUs, reflecting strong local demand. Whether you want space for family, a long-term rental, or a dedicated home office, a properly built ADU adds real value to your property. We serve homeowners across Menlo Park, Palo Alto, Atherton, San Mateo, Redwood City, and surrounding Peninsula communities. Call us to talk through what your lot can support.
