From Our Clients

  • Matt Baranowski
    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.

  • Testimonial-s3da design - 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.

  • peter knowles
    I am very pleased to write this letter of recommendation for S3DA-Design's structural engineers. During the period of H1, 17, I have been able to closely interact with them on a complicated building package consisting of both structural & construction drawings for an important new build development. I have observed their capability to quickly grasp the concepts I have in mind and efficiently implement the same to solve the engineering needs of the project. their rational thinking and ability to address all points of clarity is impressive and so I have no hesitation in providing this recommendation for them.

  • Ricardo
    S3DA-Design's engineer has recently worked for us in a substantial house renovation project which comprised a loft conversion and a side extension on the first floor. He produced a clean and elegant structural design and provided all the necessary documentation to comply with building regulations including layouts, materials, etc. We had to deal with a difficult building control officer, and he was patient with the iterations and always quick and resolving in his responses. We are very happy with their work and would definitely work with them again. I can recommend them in the strongest terms.
