Few additions improve daily life as much as a sunroom or porch, and in Middle Tennessee they get used hard. Spring and fall are made for the outdoors here, but summer humidity, mosquitoes, and afternoon thunderstorms send people inside fast. A well-built sunroom or screened porch bridges that gap. Nashville Build Group has been adding them to homes across Nashville, Franklin, Brentwood, Gallatin, and Mt. Juliet since 2007 as a licensed Tennessee general contractor (License #BC-71284) and NARI member.

We build the full range, and the right choice depends on how you want to use the space. A screened porch keeps the bugs out while you enjoy a breeze, ideal for Nashville's long shoulder seasons. A three-season sunroom with large windows extends your comfortable months into cooler weather. A four-season room, fully insulated and tied into your HVAC, becomes true year-round living space that counts toward your home's square footage. We also build classic covered porches and outdoor living areas with fireplaces, fans, and stained tongue-and-groove ceilings that suit Nashville's traditional and craftsman-style homes.

The difference between a sunroom that lasts and one that leaks is everything you don't see. We pour proper footings and foundations rather than setting a room on an undersized slab, we flash and tie the new roof into your existing roofline so water sheds correctly through heavy Tennessee rains, and we size headers and posts to carry real loads. Cheap prefab kits and bolt-on enclosures routinely fail at the roof connection, and we replace plenty of them. A sunroom or porch often pairs with exterior renovations or new windows and doors so the addition blends seamlessly with the rest of the house.

If you are weighing a sunroom against a more enclosed space, our home additions and design-build teams can compare the options, costs, and permitting for your specific lot. Because these projects involve foundations, structure, and often electrical, Metro Nashville permits and inspections apply, and we handle all of them for you.

Every sunroom and porch comes with a free written estimate, a fixed-price contract, a realistic schedule, and our 2-year workmanship warranty. Call (615) 555-0149 to start designing your outdoor living space.

Frequently Asked Questions

How much does a sunroom or porch addition cost in Nashville?

Screened porches in the Nashville area typically run $20,000 to $45,000, three-season sunrooms $30,000 to $70,000, and fully insulated four-season rooms $70,000 to $120,000 or more. Foundation work, roofing, and finishes affect the total. We provide a free written estimate based on your design and site.

What's the difference between a three-season and four-season room?

A three-season room has windows and a roof but is not insulated or connected to your HVAC, so it is comfortable in spring, summer, and fall but cold in winter. A four-season room is fully insulated and climate-controlled, making it usable year-round and counting toward your home's heated square footage. We help you choose based on how you'll use it and your budget.

Should I get a screened porch or a sunroom in Tennessee?

It comes down to how you want to use the space. A screened porch is perfect for enjoying Nashville's breezy spring and fall while keeping mosquitoes out, and it costs less. A sunroom gives you a cleaner, weather-tight room that extends into cooler months. Many homeowners love a screened porch for the climate here, but a four-season sunroom adds the most usable space and value.

Do I need a permit for a sunroom or porch in Nashville?

Yes. Metro Nashville requires permits for sunrooms and porches because they involve foundations, structure, and often electrical work. We pull all required permits and coordinate inspections through Metro Codes, so your addition is fully legal and properly tied into your home.

How long does it take to build a sunroom or porch?

A screened or covered porch usually takes three to five weeks, while an insulated four-season sunroom typically takes six to ten weeks because of the additional foundation, insulation, and HVAC work. Permitting adds time on the front end. We give you a firm schedule at contract signing and a dedicated project manager throughout.
