Get matched with top building designers in Discovery Bay, CA

"Very honest engineer. He performed a mandatory seismic inspection that was required for the city of Hayward. There was no foundation issue whatsoever. Before Mr Padir did the inspection I had a retrofit company look at my building and they told me it would cost $58k to fix the problem and I almost fell for it. It turns out that one joist was rotten from a sewer leak that was repaired. It is hard to find honest people these days. I am so glad it is only a cosmetic fix and a sister joist installed next to it to relieve the pressure on the building. Thank you once again Mr. Padir. Excellent job and quick turnaround."

"Esther is very professional and detail oriented. She is very skilled in design and does a great job taking care of the permits. I would recommend them."

"We hired Shilpa to design an addition and remodel to our existing house in Fremont and we had a wonderful experience working with her. She listened and understood our needs, and designed the house of our dreams in the limited area that we had. She gave us many different design options in the beginning and made many revisions as per our requests. She even helped us with the city permit process and made revisions as per city requirements. The final result turned out beautiful, she used every inch of the space and the addition looks very much part of the original house. I am enjoying my beautiful house and get complements from everyone. I am very happy that I hired Shilpa and her team for my project and would definitely recommend her to others."
