He gave us a…read morerough cost for what we should expect to pay a contractor for the labor after reviewing our house. I'm so glad I never hired any of the contractors before Efrain's consultation! I hired Efrain to create a plan for the removal of an interior wall after speaking to contractors who's prices seemed too high. Efrains price for engineering was very competitive and I had checked with 3 others. As he measured the house/rooms, the conversation kept progressing, we decided to open up the drywall further to make some decisions. Turned out it wasn't a load bearing wall. This gave us more options that could reduce the cost & scope of work. SO he gave us his price for consultation instead of making drawings, then proceeded to tell us what would be required by the city, what many homeowners might normally choose to do, what he legally has to tell us, and how safe our decisions would be. We decided to do it ourselves. Plus, he continued to take our phone calls and reviewed photos along the way answering any other questions we had. He was super helpful, very generous with his time and knowledge. Good to have an engineer on your side.

Working with Miguel of Glilsamex was like working with a close friend. His service is very…read morepersonalized with respect to what their clients want. Miguel was able to envision and plan out what you are thinking but not able to draw out yourself. Miguel has unique and creative ideas to enhance your project/design and is also diplomatic and persistent with obtaining permits and plan approval. He is always in communication in keeping you abreast of the progress with the City Planning. Miguel also coordinates with others involved in the plans, regarding engineers, building contractors, landscape designers, etc. From the design to coordination with the city and pulling permits he takes care of the process, I thoroughly enjoyed working with Miguel and his company.

From start to finish, the team was exceptionally professional, responsive, and creative. Every department in the company functions like a well-oiled machine -- each person knows their role, and together they bring real results. Their use of fire-resistant and waterproof materials gave us peace of mind, and the city approved our plans without delays. That says everything about the quality of their documentation and execution. Whenever I had questions or needed support, they responded the same day -- no matter how big or small the issue was. I've already referred them to my sister, and they're now in active discussions about her project as well. Huge thanks to the entire team. You've proven to be thoughtful, reliable, and extremely talented professionals. I'm truly grateful for the experience and will absolutely work with you again.

Although OCA delivered their part on time, the construction process took longer than expected and I felt that I was supported by OCA every step of the way whenever I needed something from them.

I started with little knowledge of the process and only now do I realize how much value Kirill brought to the table. Thank you Kirill and the team!

We found Greg and were super impressed with his commercial architectural work and his general construction background too. He took charge and had the foresight to line-up a structural engineer. He was mindful of our budget and costs (very important). When you hire a professional, you're looking for someone you can trust to come in and take the load off your shoulders. He was willing to do that for us for which we are truly grateful! However, in the end, the project did not go forward as planned due to a myriad of financial considerations and the above-mentioned complications. But we are thankful for his time and efforts! He's a pleasure to work with. Thanks!

Found Letter Four online and read glowing reviews like the ones here... I should have looked…read morecloser. Having worked with them for 2 years, I now realize most of these reviews are either (1) 5+ years old or (2) from people who work there - Alex S, J M, etc. I spent about $120k and the last 2 years on a 4-bedroom remodel with Letter Four. I have *nothing* to show for it. No plans, no permits, nothing. Just a home that I cannot live in with some holes in the walls and ceilings (they just enough minor demo that I can't live there and then they disappeared - fun!) What I do have are shady invoices (they pad their invoices, double-charge you, refuse to send you receipts even after you ask 5x, charge you for everything they can with a 20% markup - Ubers, printing fees, software fees, etc). What really bothered me is that they pay their Project Managers almost nothing and then they charge you $200/hr for those PMs work. When I tried to do calls with them to understand the invoicing, instead of listening and admitting their mistakes when they very clearly double-charged me for the same things - they yelled at me. The owner Jeremy talked over me the entire call. (To his credit, he did apologize for not letting me get a single word in - he said something like "I've been told I do this to women"). If you want to work with two really arrogant people who want to talk a lot about how great they are and how right they are but won't listen - by all means, sign up to work with these folks. The work itself isn't just subpar and sloppy - it's actually unusable. They were constantly making mistakes - you'd send them measurements and then get the plans and everything would be the wrong size. I never got a window schedule that had windows that matched the plans. They never got approval for a permit for the plans they created. They made so many mistakes, it's laughable. I hired a new Engineer and Contractor who both can't stop cracking up about Letter Four's work. "This isn't even to scale! Look, they have the downspouts at the highest points of the roof! Look at this - that part must be a joke, right?!" For the prices they charge and how arrogant they are about their experience, they deliver really sub-optimal work. They claim their high hourly fees and high-end rates will make your remodel easy for you - but I found that working with them is 5x more work than with my new contractor. (Message me if you want his info - he's *amazing*). Finally, their design aesthetic is really cheesy. It doesn't match any of the photos in their portfolio. All their design proposals felt something you'd see in a cheap flip. It was a total waste of money to pay for a "design + build" firm because I ended up designing every inch of it myself. Another reviewer called them "awkward" and I 100% found that to be the case. Their online portfolio is great, but actually working with them is a total nightmare on every level. Most people don't love their contractors - but you will LOATHE these people. I guess if you want some cool horror stories about your remodel, this is the company for you!

From the outset, her aesthetic vision and design instincts were perfectly aligned with ours. She listened to our wants and needs and translated them into an architectural gem. The interplay of natural light and air flowing through each space creates an open, inviting atmosphere where function is balanced by understated elegance. During the construction phase, Gabbi was consistently available to address issues that arose and problem solved them to make sure that every detail looked intentional. She guided us through all the material finishing choices and her recommendations were always superb and mindful of the budget. Even her plant selections for the landscaping completed the look of tranquility and simplicity. Now, years later, we appreciate what has become a timeless sanctuary.
