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 Junior ADUs (JADUs) in Los Gatos, CA
A Junior ADU, or JADU, turns unused space inside your existing San Jose or Menlo Park home into a separate, livable unit up to 500 square feet. GS Design and Build handles the full scope: site assessment, permit-ready design, city submittal, and construction. JADUs must sit entirely within your home's existing footprint, including an attached garage, and require their own exterior entrance and an efficiency kitchen. In the Bay Area's high-density housing market, a JADU is one of the most practical ways to add rental income or house a family member without expanding your home's footprint. San Jose and Menlo Park both allow one JADU per single-family lot alongside a standard ADU, so qualifying homeowners can maximize the use of a single parcel. Our team knows the local plan-check process and builds to California's current JADU standards. Call GS Design and Build to find out if your San Jose or Menlo Park home qualifies.
