Expert Home Additions in Williamson County, TN

Home additions give Williamson County homeowners a way to gain square footage without leaving a neighborhood they love. At Backyard Boys Construction, we handle the full scope of addition work as a licensed general contractor. That includes room additions, primary suite expansions, sunrooms, and attached garage conversions. Williamson County's rapid residential growth means many existing homes were built on lots with room to expand, and local building codes require plan review and approval through the county or the relevant municipality before work begins. We manage that coordination so you do not have to. Our process starts with a site review, moves through design alignment, and finishes with a final walkthrough to confirm everything meets code and matches your plan. Whether your home is in Franklin, Brentwood, Spring Hill, Nolensville, or Fairview, we bring the same structured approach to every project. Call Backyard Boys Construction to talk through your addition and get a clear scope of work.

Jason and his team of craftsman work diligently, they kept the timeline they committed to, and they did high-quality work. I recommend them unconditionally for construction work in the middle Tennessee region. Our project is in Franklin. We could not be more pleased.

Jason and his crew did an excellent job! Great to work with on discussing options. They re-worked our porch railings, stained our porch ceiling, replaced our front door and installed our pool coping in a timely, professional and reliable manner. I will definitely use them for any future remodels or projects. Thank you!!
