Jason and AT6 were incredible to work with! We’ve remodeled 7 homes in our lifetime, and AT6 was by far the best experience we had! They took great care in transforming our home, which has been in our family for over 60 years, to one with modern features while keeping its historical character. Project was on-time and on-budget and Jason and team worked collaboratively with us to design and build our new home. Huge benefits using a Design-Build firm and AT6 is top notch in shaping your vision while helping you stay within budget.
AT6 Design Build has been a true partner of ours over many years and multiple remodels. Jason and his team are professional, super responsive, and really give their 100% to every job. Their designs and construction are really high quality, unique, and beautiful. They also think through eco-friendly options and present more forward-thinking solutions which makes your home stand out. We absolutely love Jason and his team!
If I were to do another remodeling project, I would use AT6 again without hesitation. Fair, honest, competent, responsible and fun to work with. While the final product (the destination) is what matters the most, the process (the journey) was positive and constructive, marked by frequent communication and sound problem solving.
Everyone at AT6 was great to work with and did their best, demonstrating great positive attitudes and problem solving skills.
I’m 66 and over the years I’ve worked with a variety of very good architects on various residential & commercial projects. Jason is terrific to work with. He has wonderful design sensibilities and is creative. He also has construction experience as a contractor, so he has a real understanding of the nitty gritty that gets projects built cost effectively. His construction experience also yields well-detailed plans & specs that can be readily be bid by contractors. Our project with him was in San Francisco, and there was a real question whether we could get it approved at all. Jason had excellent judgment on how to design and present it so that the City would go along, and his knowledge of the Dept of Building Inspection got us through the process crisply and efficiently. Other architects we interviewed had predicted a much more difficult time than we experienced with Jason. Highest recommendation.
Overall, a tremendously positive experience and house turned out exceptionally well. I would highly recommend AT6 Design Build. This project far surpassed my expectations. Jason has been an exceptional partner! I couldn’t be happier with the outcome. It truly is my dream home.
We switched to AT6 in the middle of a new house construction project, as we had persistent problems with our prior architects. Jason thoughtfully and delicately maneuvered the situation by working within the framework given by the existing design, but contributing new angles and direction wherever it was appropriate. The interaction between Jason and our contractor was seamless. Jason’s dual experience as a builder makes him very qualified to solve challenging issues. He never shied away from technical details that the construction crew requested and played an essential role in making our project progress without major hiccups. Jason always had interesting viewpoints to contribute and had suggestions and solutions that we hadn’t thought of before. We would highly recommend him as an architect.
We met with them with a list of dreams for our new space. It was to be a full flat with bathrooms, kitchen, separate entrance, and (eventually) a separate address. They mocked up a few ideas with our original idea of building out in the garage. They incorporated all the current SF building code requirements automatically. We looked at all the different designs, and decided that we couldn’t get what we wanted with it. So, we started over from scratch, thinking of a third floor addition. Jason and John immediately showed us a ball-park budget and made sure that we knew what we were getting into. They took my dad’s concept ideas of what he wanted (morning light in the bedroom, an open airy feeling, etc.) and made it into a fabulous plan for our third floor. They had about three fundamentally different designs, met with us and we refined it from there in a series of a few meetings. They had great ideas and recommendations about picking all the products so they could incorporate it into the design early. They also have helpful spreadsheets and lists to make your checklists easier. Personally, Jason and John are respectful, great listeners, interested and easy to talk to. Construction can be a stressful process, and we were not immune to this at all. They remained kind and understanding, patient and approachable with all our questions and items that always came up.
Jason and his team at AT6 were great to work with. We renovated a single family house in San Francisco (down to the studs, full house renovation), and very much enjoyed working with Jason. Jason’s skill set (he is both an architect and a builder) is rare, and it makes for much better execution. Highly recommend!
AT6 were the quintessential professionals. I trusted them, their workers and their judgement. Overall, it was a very positive experience and I would absolutely recommend them. I was most satisfied with being able to trust their judgement and design sensibilities. I was also satisfied with their ability to bring me in at the right time and the right level of decisions
Jason and the AT6 design team have been the fantastic creative team behind the complete interior and exterior renovation of our home. We’ve worked with Jason for 10+ years and he’s truly transformed our house into everything we envisioned (and more). Since he was a contractor prior to becoming an architect, he balances creativity and practicality into his designs in a way that few others can. And his design capabilities are endless given he designed our home renovation as well as our recent backyard update. On top being a great design/build team, Jason and his team are extremely responsive and a pleasure to work with. They work with your style to create a variety of options for projects and adapt designs based on feedback and their their wealth of experience. I highly recommend working with Jason and his team on any renovation or new construction projects as we could not be happier with how they transformed our home!
We have done two large remodel projects with Jason and the AT6 team and I could not be more pleased. His design sense and communication are second to none. I have used other contractors and I hope never to do so again. His costs are accurate and fair. He has a great sense of what things will cost and whether your budget will get you what you are hoping to have. Both projects were on time and on budget. There is nothing secretive with Jason. He can explain the work to a non construction person, he is available when we needed him for questions and his follow through is bar none. Both homes we remodeled with him came out lovely and we get compliments all the time. And they have held up over time with no issues. I have zero reservations about recommending him. You will be pleased with the process AND the results.
Jason is an exceptionally talented designer who pays extraordinary attention to detail. Regarding dealing with the labyrinthine City bureaucracy, Jason was able, on a secondary egress issue, to accomplish what three other architects told us wasn’t possible. After living in our house for three years we wouldn’t change a thing -- the highest compliment I can give.
We had Jason and his team complete a substantial remodel, including adding a second story and an addition to a guest house. His team was easy to work with, very communicative, and we have been so pleased with the results!
AT6 has completed a substantial renovation including both design and building on our home in Marin. We are delighted with the results and the process. Jason Langkammerer developed a wonderful design that fulfilled our needs. This was a reiterative process with the plans evolving as we assessed goals. The building phase had delays because of supply chain problems, but the builder was able to accommodate and keep the project moving. The physical results are of high quality, actually outstanding. Most important is the wonderful culture of AT6. We had great confidence in Jason and all of the others involved in the project. They were responsive to us and understanding of the unavoidable difficulties that we lived through during the renovation.
Jason and his team did a terrific job on an extensive remodel project of our flat. Jason has great taste and a good sense of “bang for the buck”. I found I could trust his judgment. People really loved how it all turned out - Curbed SF even chose to feature it on their website! The AT6 people do high quality work and are a pleasure to deal with and we would not hesitate to work with them again.
We worked with AT6 to remodel our downstairs, including a bathroom and a bedroom. They were very well organized, prompt in communication, and the project finished on time to the original timeline. The final remodel is beautiful and everything we wanted.
