Happy Clients

    S3DA Design did a great job for my team and I on a structural engineering analysis. Mos was very responsive and easy to work with. The work product he provided was excellent and thorough, and the project plans we submitted passed a tough Building Department review. I would highly recommend S3DA and Mos.

    I really needed someone to put together and guide the process as far as getting the architect, the engineering, all the pieces together, find the contractor to do the buildings, someone who had the experience dealing with DSA, all the submitting, all the paperwork, getting the process and the procedure going was really as big as the building itself. I most certainly would work with S3DA-Design again. My experience was great with them, I thought it was a total team approach, I thought all the individuals were great in getting the information out, the request for information to be able to build the building, the budget, the whole process just was very well orchestrated by S3DA-Design. I honestly don't know how you could have done it any better, I appreciate all of your time, help, and willingness to drop everything and come to the site, talk to me and make sure that my concerns were met, and deal with, and I thought it was a pleasure dealing with everyone in your team.

    Mos is an exceptional architect of S3DA Design. I have been developing for the last 9 years, have had a few architects over the years, Mos has a rare combination of competence and common sense, plus he is very sharp, quick and a pleasure to deal with. Builder's dream come true.

  • David Waller
    We can’t thank S3DA-Design and its structural engineer Kale highly enough for coming to our rescue when we were in desperate need of floor plans, fire safety, electrical and air conditioning plans for our new work-space. Unfortunately, our Architect had only partly completed our plans due to illness and we were thankful to have found them who provided us with what we needed with minimal turnaround. We had all our plans within 5 days!! Thank you so much again, we are extremely grateful and would highly recommend.
