"We have a home that was built in 1930, that is loaded with charm but needed some adapting to our family’s needs. It had two too many doors and one large window that we never used because it looked directly at the neighbor’s driveway! We also needed to have new windows and floors installed, custom bookshelves built, and of course new paint. We decided to hire Fred because from Day One you could tell he was someone that was knowledgable and someone you can trust. Having someone you can trust to do projects in your home is so important because they become a part of your lives for at least a month or so! Fred took care of everything: the supples, installation, paint, and making sure that the brick installers completed the job successfully as well. I now have an office that used to be an “all weather” porch that I can actually be in all day, another office/second bedroom that has more wall space thanks to the seamless work Fred did in closing up a large window and door (not to mention it was with plaster!) He was really precise in doing “delicate demo” since we were trying to save as much of the old house charm as possible. We were even able to use one of the doors in my new office, and it looks beautiful. Cost wise, everything was up front and there were no surprises (even though he was very gracious about us adding items along the way (like extra plugs and installing a storm door). We also had our attic re-insulated and part of our floor lifted which Fred took care of as well. He communicated with us every step along the way, which is also so important. We hope to have a custom closet installed in the near future and will definitely call Fred to do that project as well! 10/10 recommend Fred Oakley for your home renovations!"

"TJ and his team remodeled my elderly parents' bathroom so they could safely age in place. Removed super old shower and tub and then installed new shower complete with new tile. Also ripped out old floor and installed new tile. It was a major upgrade and my parents are BEYOND PLEASED with both the high quality workmanship and attention to detail they provided. They are a blessing to work with and truly canâ  t thank them enough. This was the second major project they have completed for us and would recommend them to anyone, anytime."

"Best Builder in Nashville!! I do not do reviews but this experience has changed that for me. Hired BHB and was impressed from the first meeting. Gary was genuinely interested in our home project, affordable pricing, and educating us on the process. His professionalism, working consistently to finish the project, attention to detail and cost awareness was valuable to us. His workmanship is amazing. We are extremely proud of our new addition. In a time where you never know if your contractor is good, Gary and the BHB crew are the real deal. I highly recommend him."

"I hired KM home Improvement company for a kitchen remodel and had an excellent experience. The planning was easy and efficient, without neglecting any details, and the cost was very reasonable. During the remodel we encountered a number of issues that could not have been predicted, such as rot in a wall, 2 inches of concrete under the floor tiles, a leaky roof and an entire week of ice and snow that paralyzed the entire neighborhood and made it impossible to come up to the house. AliReza, the owner, not only took on these extra projects, but he managed to keep surprisingly close to the intended timeline as well as to the projected costs. We ended up with a beautiful kitchen and a house in healthier condition. Working with AliReza is like working with a partner who listens, advises, and makes it all happen. His concern was for us to live in a place we wanted to live in. AliReza started the project the day he had promised to start, his people showed up every day at the same time (except for the week no one could come up the hill), and we talked on an almost daily basis. We have a couple of other projects we will have to take care of in the next couple of years, and we already hired KM Home Improvement for an upcoming one. I have never had such a positive experience with a home improvement project, and I have seen the stress of kitchen renovations in my friends. I, on the other hand, annoy my friends with my raving reviews about my experience with KM Home Improvements."

"A lean too or an additional covered parking space was added to our carport. The addition is very well built and looks great. We had them cover the entire carport with the same roofing, siding around the top of the entire carport and added gutters. While doing all this work they checked for any wood that might need replacing. Some wood was replaced while other pieces only needed a few extra nails. Loved the completed job."

FAQs for addition to existing structure building service projects in Brentwood, TN

You can typically raise your roof by four to eight feet, depending on your home's structure and roof design. The exact amount depends on factors like roof slope and framing support. Raising the roof creates additional interior space, enhances natural light, and increases your home's value. Consult a professional to determine the feasible height increase for your home.

Yes, you need a building permit to raise your roof. Obtaining a building permit ensures your project complies with local building codes and safety regulations. A professional contractor can assist with the permit and inspection process and ensure all legal and safety requirements are met. Your contractor will be familiar with building codes in your area, which can differ between cities or states.

While it's possible to raise a flat roof, it requires extensive structural modifications. Flat roofs lack the attic space and support structures of pitched roofs, so raising them involves significant engineering to ensure safety and durability. This process can be complex and costly, so professional assessment is essential before undertaking a project of this magnitude.
