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.

GS Design and build did an amazing job uplifting my garage. Gheri was the most responsive of the contractors I got quotes from and he was very quick to respond with a reasonable estimate. He was always reachable and ensured the team was very punctual. His crew did a great job completing the job and handling surprises. I didn’t have to contact Gheri for anything during the job. The final work quality was great and my garage looks great! I will highly recommend GS Design and Build for your home improvements Update: i did a bathroom remodel with them 6 months after the garage upgrade and it was amazing! The team has remained consistent with their quality and workmanship!

We used GS Design and Build for a room addition in Redwood City and couldn’t be happier. Geri helped us figure out the best layout for our new sunroom and made sure the style blended with the rest of our house. Her crew worked clean and fast, and everything passed inspection the first time. The project wrapped up on schedule and within our budget. The space gets amazing light and has quickly become our favorite part of the house. If you’re in the market for a room addition contractor who truly listens and executes, don’t look any further.

Just got my home addition done! GS design helped us build a new bathroom and a new master bed in new construction. Everything was fully licensed and Geri managed everything at his end. I found Geri on Nextdoor and was nervous before signing him up but to my surprise, I couldn’t have asked for more! He has a lovely team of people who specialize in what they do. Geri cared for me and made sure I am satisfied at each step. He gave me a good run down of what he plans to do in the coming week which was very satisfying. Geri’s rates were also very competitive and he was reasonable when the work order changed. What I liked about Geri a lot is also that his interior designing skills are also very strong so he guided us when the size of the window was off or in making lovely choices of the flooring. You can trust Geri blindly and go with him. You will not regret it. Thanks Geri, for all the great work.

We live in Redwood City and reached out to GS Design and Build for a second-story room addition. Geri coordinated with our structural engineer and managed the project with confidence. We were impressed with how smoothly everything went. Her communication throughout the process was excellent. The new space has completely transformed our home and given us the extra flexibility we needed. Top-notch room addition contractor and a pleasure to work with.
