We loved our experience and wholeheartedly endorse Winder Gibson to anyone looking for a full service architecture firm. From the outset, Geoff and his team demonstrated an exceptional understanding of our family's needs, which they transformed into a beautiful house design that resonates with our aspirations and lifestyle. We are currently transitioning to the construction phase, and are excited to raise our family in such a thoughtfully designed space. Also, Geoff and team are true experts at navigating the San Francisco permitting process. They efficiently moved us through permitting, both reacting to feedback from the city and helping us manage our neighbors. Honestly, we could not have permitted the house without their guidance. In a city where building homes can be difficult, the one two punch of beautiful design + the knowledge and skill to get it across the line was invaluable. We are so appreciative of Geoff and team.

We worked with EDR to completely remodel a duplex into a single family home that hadn't been…read moretouched in 60 years. Eddie and Sarmad did a fantastic job in delivering the project. From the start of the design project, they used high quality sub contractors for design, engineering, and all the trades in the house. Fernando, our project manager was incredible. He approached the project with a keen eye for details and took total ownership over the sub contractors. He would stop by almost every night to ensure that the subs were performing their work and not leaving or damaging any other contractors' work. Sarmad is a problem solver. He sees an issue and thinks through how to solve it, then presents clear options to choose from. Throughout the process, we were not surprised by unanticipated expenses - all changes were clearly explained and we had the option to make changes via clear change orders. EDR uses Buildertrend for all program management and billing, which made payments, change approvals, and scheduling tracking seamless. While this sounds like a basic requirement in 2026, not all contractors use these services which just adds friction to the process. We couldn't recommend EDR more for the quality of work on our house, the schedule execution, care for detail, and just taking care of our project. Along the way, we never felt nickel & dimed, and the value of their services definitely exceeded our expectations.

From the very beginning, we were impressed with Senthil, Ryan and other members of Zenith team's level of professionalism, prompt response, architectural knowledge and effective communication.This level of service was seamless through our entire engagement with Zenith Engineers Inc., from obtaining the building permit to successfully passing all necessary inspections by the SF Building Department. No one questions their architectural work because they are so good at what they do. We had some initial concerns after reading negative reviews, but as the project progressed, it became clear that those comments were based on personal grievances, rather than valid concerns. The team at Zenith Engineers Inc. has a high level of professional ethics and integrity. Zenith's management team had explained to us early on in the project, the strict adherence to code and compliance was paramount throughout the project. If Zenith compromises to satisfy unsatisfied clients, the building will end up being non-compliant and more importantly unsafe. We truly appreciate Zenith's commitment to quality and integrity, even if it means earning a few negative reviews along the way, which seem rather unfair to them as they are simply doing their job. I am extremely satisfied with the professional and excellent work the team at Zenith Engineers Inc. provided us and will hire them in a heartbeat for all our future structural and/or seismic engineering needs. Thank you Senthil, Ryan and the Zenith engineering team for your professionalism and support. It was our best decision to work with you and experience such high standard of professionalism, work ethic, and integrity.

After having used Zenith for multiple projects in the last few years, looks like it's finally time…read moreto look for someone else for the next one. We started using Zenith because of its responsiveness and effectiveness when it came to structural design. With them as part of our team, we were able to keep up with the City submittal and response timelines we had set. Fast forward to today, and we can't get a hold of anyone. When we do, it's always an excuse for why they didn't respond, without a resolution. We sent them the last City comments 30 days ago and have yet to get anything viable to re-submit back to the city. Given that this is a 30-unit hotel project, going with a different firm now will mean a complete re-design of the project; an absolutely painful exercise that will set us back months. Zenith knows that. So it's absolutely shameful for them to act in a way that would even suggest that our only choice is to get the entire project re-designed by another firm just to have it keep moving forward. So much for "we respond to emails within 30 minutes and always answer phone calls" as outlined on one of their online profile. Knowing how we were treated on this round of City comments and the fact that the entire company seems complacent about what they try to embody in their rhetoric, I would stay away for any future project.

Brian V. came over to check out our house and to see if our expectations were realistic. He was very calm and organized. We found him very knowledgeable, especially about the San Mateo County permit & planning department. We interviewed a couple of other architeture firms, but found Brian at The Kastrop Group to be the best. Once we hired Kastrop, Brian quickly set up a time to come measure the entire house. Our 80 year old cottage had no central air/heat, so Brian referred us to an engineering firm that would help work out all the  computations that the permit department would need to approve this addition. As we moved through the architectural design process, Brian came up with solutions that would give us what we needed, along with a few suggestions that would provide more storage near our new second bathroom. We found Brian and Kastrop to be very accomodating with no drama. We like it when there is no drama. Once the architectural drawings were approved, we wanted to know if we had budgeted enough for the renovation. So, Kastrop had a General Contractor look at the plans and visit our house to give us some preliminary numbers. This was a big help for us and we were so thankful for this extra step. The Kastrop Group is an outstanding architecture firm that took us through the entire architecture design process with a gentle hand and no drama. We were grateful for their professionalism and their recommendations. If you are considering renovating your house, your first stop should be The Kastrop Group for impressive architectural expertise and being a great partner to navigate the county permit process.
