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.

Recently had the pleasure of working with Golden State on a restoration project, and I must say, they surpassed all my expectations. We hired them to handle the design, drafting, engineering, and permit acquisition, and their expertise and professionalism were truly outstanding.

From the moment we brought Golden State on board, it was clear that we had made the right choice. Their team, led by William, displayed an impressive level of knowledge and skill throughout the entire project. Their attention to detail and commitment to excellence were evident in every aspect of their work.

They took the time to understand the unique requirements of the restoration project and delivered a design that perfectly balanced modern functionality with the preservation of historical elements. Their ability to capture the vision of the project and translate it into a comprehensive plan set was truly impressive.
They paid meticulous attention to every detail, ensuring that all specifications were accurately represented in the drawings. As well as addressing the structural challenges.

One of the greatest advantages of working with Golden State was their ability to handle the often time-consuming and frustrating process of obtaining permits. They took charge of the permit acquisition process, liaising with the necessary authorities and ensuring that all documentation was submitted promptly and accurately. This saved us a significant amount of time and allowed us to focus on other aspects of the project.

Throughout the project, William and Yasir were reliable and responsive points of contact. They maintained open lines of communication, keeping us informed of progress, addressing any concerns promptly, and providing valuable guidance and expert advice when needed. Their professionalism and dedication to client satisfaction were truly commendable.

Thank you, Golden State Design and Engineering Firm, for your exceptional services!

I hired William to design my ADU for me! They are very responsive and efficient! After we got the permit from the county, they are still willing to follow up if I need to make some changes to the permitted plans. And when my contractors have questions about the plans, they are willing to spend the time to discuss with my contractors. I really appreciate their help!!!

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.
