We are a locally owned and operated company that values honesty and integrity and treats your home as if it were our own. We offer a variety of general contractor services that are customizable to each individual project. We specialize in additions and remodels, but also offer a wide range of expertise for a variety of other projects. We pride ourselves on the quality of our work as well as our commitment to outstanding results. We look forward to building lasting relationships and guarantee your satisfaction!

"We hired Diamond in the Rough Construction for a home addition, and while the finished result looks good at first glance, the process was full of issues and cost us much more than expected. We chose Diamond because of Abby, the salesperson, who was incredibly helpful and responsive. However, she left midway through the project, and we missed her support. Addison, the project manager, did his best but was left to handle more than he should have. The owners, Joe and Mike, were completely absent ? no check-ins or follow-ups, even when major issues arose.There were significant mistakes, like framing the windows to the wrong size, and we were blamed for "approving the wrong windows." HVAC was also forgotten until after construction started, forcing us to pay thousands more. The trim was poorly finished with putty that didn?t match the color of the pre-painted trim, and the solution was simply to cover the nail holes with a paint pen. In the end, we can?t recommend Diamond in the Rough"

Elite Design and Renovation is a small Columbus company that takes pride in quality and customer service.

"Elite Design completed two projects. The company installed over 3500 sq ft of lvt flooring in a commercial space for my business. The project was completed in two days (weekend so not to interfere with business) with a full crew installing. Intricate cuts were required and the result was professional. The second project was crawl space insulation in my home’s crawls space. Again the crew worked steadily and completed the job in just a couple hours. They cleaned up when done and I was pleased with their professionalism. Highly recommend."

Addition to existing structure building services FAQs

How far you can push a room depends on the structure you choose. A cantilevered bump-out can extend 24 inches before building codes require its own footing or foundation. Anything longer needs engineered support and a permit. Check local codes or consult with a structural professional before finalizing plans to ensure your design remains safe and compliant.

Most bump-outs are completed within one to four weeks, even with minimal electrical, plumbing, or HVAC work. Their compact size means less demolition, simpler inspections, and fewer weather-related delays compared to a full-scale addition. Your contractor can provide a more precise timeline once they have determined the scope, materials, and permit schedule, but plan on having the extra square footage ready in approximately a month.
