Expert Garage Conversion in Los Gatos, CA

A garage conversion is one of the most practical ways to add living space to a Menlo Park property without expanding your home's footprint. Whether you want a rental unit, a home office, a guest suite, or a space for family members, your existing garage is a strong starting point. Menlo Park follows California state ADU law, which means no replacement parking is required when you convert a garage, and conversions of legally built structures are exempt from standard setback rules. That makes the path to a permitted, finished space more straightforward than many homeowners expect. At GS Design and Build, we handle the project from the first site review through final inspection. We assess the existing structure, coordinate the design, manage building code compliance including California Title 24 energy requirements, and see the work through to a finished, livable result. We serve homeowners across Menlo Park and the surrounding Peninsula, and we bring the same hands-on care to every conversion. If your garage is sitting unused, we can help you put that space to work.

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!

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.

I hired GS Design and Build for a full remodel on our home in Santa Clara and was blown away by the results. Geri provided a detailed estimate and timeline upfront, and everything stayed on track. Her design sense helped transform a dated layout into an open, modern living space. Her crew was friendly, tidy, and very skilled. They even handled a few surprises during demo without adding delays. It’s hard to find a full remodel contractor who keeps every promise, but Geri does. I wouldn’t hesitate to recommend her for any large-scale renovation project. Truly five-star work.

Patricia R Google review · September 2025

GS Design and Build completed a room addition for us in Foster City, and we’re beyond happy with the outcome. We needed more space for our growing family, and Geri made the entire process seamless. She coordinated with the city, helped with layout ideas, and oversaw every detail. The construction crew was clean, courteous, and clearly experienced. The addition flows beautifully with the original home and feels like it was always there. If you’re looking for a reliable room addition contractor who cares about getting it right, this is the team to hire. Great experience from start to finish.
