Our project was completed in the time we expected and right on budget. The team was very professional in their dealings with us and wanted to meet our expectations in all they did. We could not have asked for a better first building experience. **★★★★★ — Karen Carter, July 2017** > After looking for a builder for almost a year and having no luck I was referred to Cornerstone and Farrell . This was well worth the wait for my project. I have to say Iam so very pleased with the end result. Looks beautiful and adds a good amount of outdoor living space. The work was done in the projected time frame and on budget . If I had any questions or concerns they were addressed to my satisfaction . I would absolutely use Cornerstone for future projects. **★★★★★ — User, May 2017** > Cornerstone Design/Build Group Inc was a pleasure to work with. They were referred to me by a friend who was highly pleased with their work, and I can see why. They did a quality job, were very professional and met the budget. Always in contact & available. I would hire them again and highly recommend them. **★★★★★ — Paul Aiello, May 2017** > First, I would like to thank Farrell and Eric Gosnell for being professional builders with the highest quality of workmanship and uncompromising dedication to designing and completing every aspect of the project with an old world eye for perfection. Farrell and his family have been building homes in my area for decades and their crews and subcontractors are dedicated and long term associates who work as a team for the best interests of the customer. Conerstone Design/Build group took on a major addition to my home and constantly went above and beyond what was required to make the final product not only meet my expectations; but often exceeded them simply because it made the final outcome better. All of this plus an extremely competitive bid compared to other builders both larger and smaller; combined with genuinely warm and friendly interpersonal relationship skills made building this sun room and screened spa room a great experience. **★★★★★ — Diana Hadad, Dec. 2016** > The quality of work was very good. My in-law house is wonderful. They were caring and responsive to my questions and needs. I would use them again. **Comment from Cornerstone Design/Build Group, Inc.:** > It's easy to build a great project when everyone is responsive, makes timely decisions and selections, and work together toward the end goal; a project everyone can be proud of. **★★★★★ — Douglas Honeycutt, Aug. 2016** > Cornerstone Design Build Group provided exceptional service from start to finish. The Cornerstone team produced concept drawings for the project and made suggestions to ensure a the project was viable and at a reasonable cost. The Cornerstone team are professional, on time and capable of completing professional work at a reasonable cost. Ferrell is mindful of the budget and works to keep cost in line and project on time.

Over all exceptional experience with a contractor that I would be willing to recommend to anyone. **Comment from Cornerstone Design/Build Group, Inc.:** > Thank you for choosing Cornerstone Design/Build Group for your Addition and Remodeling Project! **★★★★★ — HU-919158, Aug. 2016** > I had used a number of builders/construction companies before finding Cornerstone. They are not only great guys, and now friends of mine, but they show up when they say they will, they only take the amount of time they promise, and the costs are what they state in the beginning. I will never use anyone else for our construction needs! **Comment from Cornerstone Design/Build Group, Inc.:** > Thank you for choosing Cornerstone Design/Build Group for your project(s)! **★★★★★ — HU-166411, Aug. 2016** > My wife and I worked with Cornerstone to build a sunroom on our house. We worked with them closely on the design and materials. They were very receptive to our ideas and we were very pleased with the final plan. The construction crew did a great job, and the quality and workmanship was excellent. The final product was better than what we expected. Very pleased with the work and would not hesitate to use them again or to recommend them. **Comment from Cornerstone Design/Build Group, Inc.:** > Thank you for choosing Cornerstone Design/Build Group for your project(s)! **★★★★★ — HU-4133158, July 2016** > does great work we added 12 ft out and 22 ft long with basement under it > for a total of 528 sq ft wife loves it and feels like she is on vacation with the windows and light.

We feel it is well built, the finish work is excellent, and the subcontractors were professional. It still looks great today. In 2012, we were ready for a kitchen update and did not consider anyone else for the job. Ferrell always listened and worked well with us in what we wanted to accomplish. He was on time, returned phone calls and kept us informed. He stayed within budget with both projects. **Comment from Cornerstone Design/Build Group, Inc.:** > Thank you for choosing Cornerstone Design/Build Group for your project(s)! ## Selected projects - [Designs](https://www.houzz.com/hznb/projects/designs-pj-vj~1812585) - Location: Not specified - Photos: 14 - [Cornerstone Homes Exterior](https://www.houzz.com/hznb/projects/cornerstone-homes-exterior-pj-vj~1807485) - Location: Not specified - Photos: 9 [See all 2 projects](https://www.houzz.com/professionals/design-build-firms/cornerstone-design-build-group-inc-pfvwus-pf~1225831195) ## Ideabooks - [Sun Rooms by CornerstoneDB](https://www.houzz.com/ideabooks/68538011/list/sun-rooms-by-cornerstonedb) — 7 ideas - [Additions by CornerstoneDB](https://www.houzz.com/ideabooks/87066346/list/additions-by-cornerstonedb) — 12 ideas - [Pool Houses by CornerstoneDB](https://www.houzz.com/ideabooks/68538273/list/pool-houses-by-cornerstonedb) — 10 ideas - [Decks by CornerstoneDB](https://www.houzz.com/ideabooks/87068293/list/decks-by-cornerstonedb) — 16 ideas - [Laundry/Craftroom by CornerstoneDB](https://www.houzz.com/ideabooks/68633157/list/laundry-craftroom-by-cornerstonedb) — 1 idea - [Staircase by CornerstoneDB](https://www.houzz.com/ideabooks/68540152/list/staircase-by-cornerstonedb) — 2 ideas - [Kitchens by CornerstoneDB](https://www.houzz.com/ideabooks/68632746/list/kitchens-by-cornerstonedb) — 12 ideas - [Baths by CornerstoneDB](https://www.houzz.com/ideabooks/68542284/list/baths-by-cornerstonedb) — 18 ideas - [Screened Porch by CornerstoneDB](https://www.houzz.com/ideabooks/68539004/list/screened-porch-by-cornerstonedb) — 4 ideas [See all 9 ideabooks](https://www.houzz.com/ideabooks/users/farrellgosnell) --- *Source: Houzz professional profile.
