They are good people, not just good builders. I like them as friends, not just as workers, but as friends.”

- Herb and Dolores Kemp, Homeowner – Daniel Island Park

If we were to build another house, they would be the only people I would go to.”

- Lee Helmer, Homeowner – Daniel Island

Every person with whom we have dealt is a really good person. Mary and I trust them completely to always do the right thing. We love the home.”

- John Gilsenan, Homeowner – Daniel Island

We have been in our house now for over a year and we wanted to take the time to let you know how pleased we are with the house. It was our first attempt building a home and the process, as you know, is always a great learning experience. Your staff is very dedicated and professional, you should be proud of the team you have put together. . . We truly appreciate the efforts of your entire staff. We have recommended and will continue to recommend your company. We wish you many years of successful building.”

- Larry and Laurie Tyree – Homeowners, Daniel Island Park

I just want to reiterate that Amy and I have been absolutely thrilled with you and your team throughout the entire process. We heard so many nightmares about building a home, that we braced for the worst. However, the whole project has moved without any glitches and you’ve all been wonderful to work with. The house is superb and we’ll enjoy living there for a long time. . . and then you can build our next house when Amy’s ready to upsize.”

- Michael Hyatt – Homeowner, Daniel Island Park

They were the greatest team I’ve ever worked with! They are a bunch of unbelievably professional and excellent group of people who care. We have done a lot of construction, and it is hard to find a company that cares the way that they do. They have done an incredible job!”

- Gregg and Ann Behrens

We are extremely pleased with the professionalism of the Structures’ team. Our design had many complicated details that were solved without the associated stress that normally accompanies an architecturally challenging project. They respected our tight budget demands and worked with their subs to get every detail right. Structures’ dedicated staff built a wonderful home for us. We would highly recommend them.”

- Steve and Carol Degnen, I’On

Structures came highly recommended, so we expected a high level of service and quality. That taken into consideration, Structures has exceeded our expectations on all levels. It’s a pleasure working with each member of the team assigned to our project. You can sense their personal interest and commitment to us and to making our home a success.”

- Steve and Carol Degnen, I’On

Structures Building Company exceeded our expectations and my being an Architectural Designer with 25 years of experience made that considerably more difficult.”

- Christopher Caponigro – Homeowner, Daniel Island Park

This has been an outstanding venture. The staff and subs have all exceeded our expectations. Being in real estate, we somewhat expected some ups and downs in the construction process. We were pleasantly surprised. The entire staff has proven that customer service and quality care go a long way. We have both commented on many occasions that after only living in our home a few weeks we would absolutely buy another home from Structures. Steve K. and the entire Structures family have continued to go above and beyond to make sure we are satisfied. It is a pleasure to do business with such a professional group. We are more than happy with our choice of builders and we feel that as our needs grow, we will continue to be a part of the Structures family. Thank you.”
