The team was professional, communicative, and responsive to our needs. We're extremely happy with the final result and highly recommend them for anyone looking to build a custom home.

I couldn't be happier with the work Golden State Design and Engineering did on my custom luxury home. From day one, the team really took the time to understand my vision and turned it into something even better than I imagined. They were professional, communicative, and always had creative solutions when challenges came up. The whole process went smoothly, stayed on budget, and the result is a home that's both beautiful and functional. If you're looking for a team that truly cares about your project and delivers top-notch work, I highly recommend Golden State Design and Engineering!

Golden state design did the design and engineering for my custom home. From the start William and his team were beyond helpful. The plans were well thought out and easy to read. Throughout the project any questions I had, William made himself available to answer very promptly. In addition to this, Golden State took on several other projects for us, and the results were just as great. William prepared all of the paperwork, filed with the county and did any revisions the county needed. I am beyond happy with their service and would recommend them to anyone. I will be doing an ADU in the near future and I can’t wait to see what golden state design can help us come up with.

The Golden State’s structural engineers saved my project. Their roof framing plan and structural load calculations passed city review with zero issues. They prioritize safety and compliance without overcomplicating things — a rare find. Highly recommend their engineering solutions!

William built an ADU in my backyard. He handled everything from planning and getting permits to construction (only the original home plan was my idea). Some jobs (foundation, roof, HVAC, electrical, stucco, etc.) were done by subcontractors, but William was closely monitoring the work during all phases and his team did a lot of hands on jobs (site preparation, framing, insulation, interior, cabinets, painting, etc.) as well. In a few instances, William came up with the solutions that saved me thousands (he figured out how to set up electrical without having to add a new panel, chose the optimal option for solar, etc.). I'm very happy with the end result and would not hesitate to recommend William and his company for any type of construction or remodeling jobs.
