Nashville, Tennessee
Additions, sunrooms and screened porches in Nashville.
More room without moving: a screened porch you use eight months a year, a sunroom off the kitchen, or a primary suite on the back of the house. We build additions across Nashville and Sumner County on cost-plus pricing, tied into the house so it looks like it was always there.
Typical range
$20,000 to $250,000+
Foundation, roof and finished square footage drive the number.
Time on site
6 weeks to 6 months
Plus design and permit time before we break ground.
Pricing
Cost plus 15–25%
Itemized, with receipts at every payment.
What it costs
Nashville addition and porch pricing.
Four common versions of this project, and what they run around Nashville. How the new roof ties into the old one decides more than people think.
| Project | Typical cost | What's involved |
|---|---|---|
| Screened porch | $20,000–$100,000+ | New porch or screening an existing deck: footings, framing, roof tie-in, ceiling, fan and lighting, screens |
| Three-season sunroom | $55,000–$100,000 | Insulated windows on a new or existing foundation, roof tie-in, electrical, finished floor and ceiling |
| Four-season room or bump-out | $90,000–$175,000 | Heated and cooled living space on a foundation, full insulation, HVAC extension, finished to match the house |
| Primary suite or second-story addition | $175,000 and up | Bedroom, bath and closet, foundation or structural upgrades, plumbing and electrical tied into the house |
Ranges are what jobs like yours have run recently, not a quote. The written estimate is the number that counts.
Where the money goes
The four things that decide your budget.
On an open-book job you'll see all of this on the cost report. Here's what to expect before you ever sign.
-
Foundation and site
Sloped lots, rock and drainage all change what's under the addition. A crawlspace or slab foundation is a big part of the cost, and we price it after we look at the yard.
-
Roofline tie-in
The hardest part of any addition is making the new roof meet the old one without leaks or an odd-looking bump. We plan the roof first and the room second.
-
Setbacks, HOAs and permits
Every lot has limits on how close you can build to the property line, and many neighborhoods need HOA approval. We check zoning, setbacks and HOA rules before you pay for drawings.
-
Heating, cooling and electrical
A heated room may need a mini-split or a bigger HVAC system. An older electrical panel may not have room for the new circuits. We find out before we price.
“Can we screen in the deck we already have?”The question everybody asks first
Sometimes. The deck has to carry a roof, so we check the footings, the framing and the ledger where it attaches to the house. If they're sound, screening an existing deck saves real money. If they aren't, we'll tell you and price a new porch on proper footings instead.
Questions we get
Before you call anybody.
Do we need an architect?
For a screened porch or a simple sunroom, usually not. We work from stamped plans where the codes office requires them. For a second story or a large addition you'll want an architect, and we can work with yours or recommend one.
How long do permits take?
A few weeks in Sumner County and often longer with Metro Codes in Davidson County. We build that into the schedule and submit as soon as plans are final.
Sunroom or screened porch?
A screened porch costs less and works from spring to fall. A sunroom with insulated glass and HVAC adds year-round living space and usually counts toward square footage.
Will it add value?
Finished, heated space adds the most. A good screened porch is one of the features Middle Tennessee buyers ask about most, even if an appraiser doesn't count it as square footage.
Can we stay in the house?
Yes, almost always. Most of the work happens outside until we open the wall to connect the new room, and we keep that window short and sealed off.
What's your minimum in Nashville?
$15,000 for work inside Davidson County, so the drive makes sense for both of us. Closer to Gallatin we take jobs of any size.
Where we work
Nashville and Sumner County.
Based in Gallatin, building additions and porches across Davidson and Sumner counties. Lake lots around Old Hickory Lake and the bigger yards in Hendersonville and Goodlettsville are where we build the most of them.
