We wanted to express our sincere gratitude for the exceptional service Kobe Structural provided…read moreduring our Junior ADU project in Porter Ranch. The project involved a complex structural modification: connecting two rooms on separate floors via a spiral staircase, which required cutting a 5'x5' opening in the second-story floor. Because this opening was directly connected to a Juliet balcony outside from a 9'x 6' sliding glass door, we were concerned about preventing a collapse when cutting the joists. We are deeply impressed by the expertise, time, effort, and dedication that Kobe and his team devoted to this challenge. They opened up ceilings and walls, calculated loads, worked tirelessly to replace the necessary supporting joists and secure the Juliet balcony. Furthermore, they followed through diligently with the LADBS to ensure our plans were approved. Throughout the entire journey, Kobe team was knowledgeable, honest, and attentive. We are extremely thrilled with the results and grateful for their expertise.

I scheduled a consultation with Eugene from STEN Engineering to discuss two very different…read morestructural issues at my house, and I was extremely impressed. The first was figuring out how to realign a very complicated roofline so that rainwater would channel properly. The house has been built and added onto in stages over roughly 100 years, so every addition and alteration made the roofline more complicated and less cohesive. I had literally spent hours sitting on the roof trying to figure out a workable solution. Eugene looked at the situation, thought it through for about 10 minutes, and sketched out an option that simply would never have occurred to me. It was practical, elegant, and made immediate sense. The consultation was some of the best $400 I've spent. The second issue was understanding how well the house is braced for earthquakes and how the existing foundation works structurally. Again, Eugene combined a strong engineering mind with real-world practical experience and explained everything in a way that I could actually understand. I almost never take the time to write reviews, but I was impressed enough that here I am writing one. Eugene is smart, thoughtful, practical, and very good at explaining complicated structural issues in plain English. I would absolutely call him again.

What stood out the most was how house solution oriented they were. they didn't just follow the typical playbook, they took the time to understand the specifics of the property and proposed smarter more efficient options that ended up saving me a significant amount of money without cutting any corners on quality or safety. Every step of the way the communication was clear, the timelines were realistic, and the work was done with precision. It's rare to find a team that combines technical expertise with this level of integrity and client care. if you're doing any type of structural work especially in LA, I highly recommend giving them a call.

A few hiccups along the way with the final permit but Sam acknowledged the mistake on his end and said he would sign off the edits in the revision phase of construction. I will give an updated review once that time comes. Quality: quality of work was good. Efficient in communication and dealing with a difficult city in a permitting process. Took about 6 months for the permits and the city kicked back for corrections 2x which is pretty standard. Value: felt his pricing was fair and reasonable Customer service: always responds to phone calls. Even after our final payment when we had questions or needed assistance. So not a "take your money" and we are done type of guy Overall impression: would use him in the future for any architectural or structural engineering jobs

We have been working with Arthur/Private Builders for about 10 months on our 6 apartments that were identified by city of Los Angeles as soft story and required earthquake retrofitting. Private Builders has completed retrofitting 5 of our apartment buildings and is close to finishing our final retrofit. I should say that it has been a very pleasant experience working with Arthur and his professional team. They knocked down all our retrofit projects one by one, A to Z, starting from engineering design, city processing, THP, and construction with their very cost efficient engineering designs. They even power washed the entire parking area after work was done leaving it shiny clean. Our tenants keep complementing their work as every construction was completed within 3-4 weeks with minimal inconvenience to our tenants. I should say they are engineers and they engineer their own projects.They are real professionals in what they do. I highly recommend Private Builders for your engineering and contractor needs on your soft story seismic retrofit project.
