"I am a contractor that has used ZS design for years now. Every job that I have done ZS has been available on a very level available. Their knowledge goes beyond just providing drawings. They are willing to work with you step by step as a question come about and any issues during the build occur. It’s nice to be able to make a quick call and they are immediate available. Highly recommend their services to builders/contractors and especially home owners who at times have trouble finding that necessary first step to begin their projects."

"Elvin is a real craftsman. He installed bookshelves in several rooms and he will do a kitchen tiling project for me later this week. He is very easy to work with and is generally responsive via text. (If he says heâ ll be there at 9:00am, thatâ s when heâ ll show up. ) Iâ ve given him access to my home when Iâ m not there and heâ s entirely trustworthy. His fees are very reasonable, in my opinion. I will definitely be using Elvin for other projects as they come up."

"The crew did an amazing job on my home addition ! "The project was top notch. They always showed up on time, they finished the project early and were willing to reschedule the final walk through multiple times to accommodate our schedule. Final project turned out great!" Everytime I asked for items to be touched up, someone was here the next day and was in and out. I know I can be a perfectionist, and they worked well with my OCD. They were recommended to us from our realtor, and the 1000 sq ft addition added more value to our home than we paid for the project ! We are very happy, and look forward to using them on our next home purchase."
