Dedication to client satisfaction has propelled the company forward and the level of service offered ensures that this recession-grown company will last.

Making informed decisions is the basis for any successful decision. Nowhere is this more evident than in construction projects in San Francisco. With discretionary permitting and the added complexities offered by the planning process, even a simple project can be unpredictable. With our experience and technical expertise, we can guide you early in the process to the answers you need.
Lending an experienced engineering eye to remodels, we ensure that you can complete your remodel/addition with utmost efficiency. With state of the art renderings we can help you visualize your project in advance and help you make informed decisions about what type of finishes you want and get a grasp of the budget early in the process.
Since mandating the retrofit of multiunit buildings in San Francisco, the Building Department has required the review of more than 6000 buildings citywide. In 2015. The city of Los Angeles has implemented a similar retrofit program for soft and "tuck under" buildings and well as non ductile concrete buildings.
Working efficiently with your architect or designer, we pride ourselves on offering the best solution with the least impact on the design. Minimizing structure maximizes the impact. From multiunit developments to small remodels, the goals are always the same. The building blocks for our problem solving philosophy are respecting the budget limitations and providing an efficient structure to seamlessly integrate with the architectural expression.
Design of internally braced soldier piles, underpinning and tiebacks and existing structure shoring is a service many firms do not provide. We at ONE Design can cater to this as part of our services. By offering foresight in the development of the project sequence, ONE Design will help leave nothing to chance.

Erevan is a talented architect, but his lack of follow up was a real challenge. We heard the same issue from some neighbors, but didnt realize the extent of the issue. If time is not a concern, then he may be a good choice - otherwise be forewarned.

I got Erevan to do a very simple drawing for a wall reinforcement. The drawings came in on time and passed through the building department ok. However, the process wasn't great. Erevan seemed to change details that we agreed to between the time we talked and the next time we spoke. Division of labor between us was also confused. And there were mistakes on the drawings that he told me to try to get through DBI, but I wasn't comfortable with that, so I had to pay him to go down there and do it himself (he fixed the drawings instead of presenting them with mistakes). I wouldn&apos

Awesome job. Provided an engineering drawing in less than a day. He was recommended by our contractor since a particular sized steel beam needed to be calculated to support my garage ceiling. He sure picked the correct one. Actual work was done without any issues. Honest and answers any questions you have.

Our first project with Erevan to design our front of the house stairs as the support structure had deteriorated. He was recommended by our contractor. He was very quick and responsive and got the job done.

The second experience with Erevan was even better. We needed to build a retaining wall on a hill in our back yar. It was not going to be an easy experience. We started with interviewing contractors and meeting with their structural engineer. After several bad experiences with the structural engineers we called Erevan directly. He immediately came to our aid and designed the wall. He even
