We hired BN Design Build for a total remodel that had major sentimental value -- the kind of…read moreproject where you don't just want a good result... you need the right partner. We started with an ~1,600 sq ft home and Ben helped us completely reimagine it into a 3,600+ sq ft dream home that our family plans to keep for generations. What stood out throughout the process was Ben's rare combo of deep technical capability and a genuinely easy, approachable working style. Ben brought significant in-house strength to the table: full architectural design (including our California room / covered patio), plus engineering coordination around soil/civil and drainage planning. That integrated approach made the process far more seamless -- fewer handoffs, fewer gaps, and fewer "who owns this?" moments. And his pricing was fair and attractive for the level of rigor and service. As the build progressed, Ben stayed close and collaborative -- not just sending plans and disappearing. He worked with us and our contractors, answered questions, and helped keep things moving. He was also extremely responsive; he typically replied within a few hours, which makes a huge difference when you're trying to keep a project on track. Ben handled submissions and permitting with the City of Fullerton and worked through City-requested changes efficiently, saving us countless hours and headaches. He also has a sharp eye for detail -- his plans were thorough, complete, and clear -- and he brought creative solutions to get the design we wanted while respecting the budget. Our taste is traditional / Cape Cod, and he did an outstanding job translating inspiration photos into a finished design that feels classic, intentional, and timeless. We went through more than four rounds of revisions, and Ben was patient and constructive the entire time -- he worked with us until we were genuinely happy. Bottom line: Ben translated our dreams into reality, and did it with professionalism, responsiveness, and real care. We recommend him and are happy to discuss our experience with anyone considering BN Design Build. We're almost done with the build and will post pictures once finished!

There was continuous and steady progress, and I usually was invited over each week to check on the progress of work. The project was well timed. The initial estimate was for around 5 months. It ended up taking 5 months and 3 weeks. The small delay was due to city permitting back-and-forth and weather, which all seemed understandable. The cost estimate was also quite accurate. We only went less-than-10% over, and generally due to things that we decided to upgrade partway through, or issues we discovered only after tearing open the walls. They also had a one year warranty on issues with the work, which they have honored with no hassle. Ultimately the company acts with integrity, and in this industry that's saying a lot.

I had the pleasure of working with an exceptional engineer Hamid who drafted the plans to convert…read moreour kitchen into an open-concept layout, which required removing a previously load-bearing wall. From start to finish, the level of professionalism, expertise, and attention to detail was truly outstanding. The engineer demonstrated a deep understanding of structural integrity while also respecting the design vision for the space. He carefully evaluated the existing structure and developed precise plans to safely support the load while allowing us to achieve the open, modern kitchen we wanted. His calculations and documentation were thorough and well-organized, which made the permitting and construction process much smoother. What impressed me most was his ability to balance technical precision with practical solutions. He communicated clearly, answered all questions patiently, and ensured the plans were easy for the contractor to follow. The result was a seamless transformation--our kitchen now feels bright, spacious, and beautifully integrated with the rest of the home. If you need an engineer for structural modifications, especially for projects involving load-bearing walls, I highly recommend his services. His expertise, reliability, and commitment to quality truly set him apart.

my experience with this company was absolutely horrible!…read morefirst of all to survey a property isn't the cheapest investment so you'd expect the service to be half way descent. This company took several hours to respond back to me to schedule appointment, that alone should have been a red flag but I still gave them another opportunity. Appointment time frame was 7:00am-7:30am, when he hadn't arrived by 8:30am I called them to see if he was late, they gave me BS that he was at the county getting info on my property. Then stated he'd arrive by 12:30-1:30pm again DID NOT SHOW! (keep in mind they already had my $1,500.00 deposit) Basically this went on all day didn't show up until 4:30 pm and the man that showed up had no idea what he was there for instead wanted to chat about his kids instead of getting the job done! I contacted there office and told them to just have him leave my property. waiting 9 hours is ridiculous. save your money and time stay away from this company!! unprofessional and unreliable, how people run there business like this is insane!

When he came out to take measurements, he offered smart suggestions that made our project more cost-effective while also adding long-term value to our home. Ramy delivered the plans ahead of schedule and took the time to walk us through everything in person. The city of Claremont's permit requirements are very strict, and it was clear that Ramy knew what the city would require. When the city had requests we didn't agree with, he communicated directly with the city planner on our behalf and guided us through the process with confidence and clarity. You get what you pay for with Ramy--his work is high quality, detailed, and thoughtful. His expertise, responsiveness, and professionalism made a stressful process feel smooth and manageable. We highly recommend him for any home or ADU project. He is absolutely worth it.
