Buying New Construction in Williamson County, TN (2026): Franklin, Nolensville, Spring Hill & Thompson's Station

If you want new construction in Williamson County, TN in 2026, your four most active markets are Franklin, Nolensville, Spring Hill, and Thompson's Station — and they span a wide price ladder, from townhomes up to custom estates. Active master-planned communities cluster by city: Franklin (Westhaven, Berry Farms, Poplar Farms), Nolensville (Fairington, Bent Creek, Burberry Glen), Spring Hill (June Lake plus a deep builder market), and Thompson's Station (Tollgate Village, Fairhaven, Canterbury). Roughly 775 new-construction homes closed across the county over the trailing 12 months (nashvillehome.guru analysis of RealTracs MLS data, early 2026).

Below, our team maps where each market sits, the price bands and lot premiums to expect, which builders are active by community, and the single decision that protects you most when buying from a builder: bringing your own representation from the very first model-home visit. Whatever your budget, the agent in the model home works for the builder — your own agent works for you, typically at little or no cost to you (how it is paid is settled per offer, in writing), on a new build.

Why Williamson County leads Middle Tennessee for new construction

Williamson County's population is estimated at roughly 275,600 for 2026, up about 1.3% year over year and up sharply since the 2020 census of 247,726 (World Population Review, 2026; U.S. Census Bureau). That sustained in-migration is what keeps builders opening new sections here.

The practical effect for buyers: a wide price ladder and meaningful differences between cities. Our team tracks active new-construction communities countywide, and two buyers with the same budget can land in very different places depending on which city and builder they start with. Here's how the four main markets break down.

Franklin: the marquee market

Franklin is the county seat, leaning toward larger lifestyle communities and custom homes.

Westhaven

Westhaven, off Highway 96 West, is Franklin's signature mixed-use master-plan, developed by Southern Land Company and planned for roughly 3,500 residences (single-family, townhomes, and condominiums) at full buildout targeted around 2031. The community has already grown to more than 2,400 households since its first homeowners arrived in 2003, so construction will continue for years. It includes shopping, restaurants, and medical offices inside the community. Active resale and new-construction listings there have spanned a wide range — from townhomes and condos as the most attainable entry up into the multi-millions for the largest custom plans (nashvillehome.guru / westhaventn.com, 2026; verify current listings, which change weekly). Builders active here include Ford Classic Homes, Legend Homes, SLC Homes (the developer's in-house division), Stonegate Homes, and Zurich Homes.

Berry Farms

Berry Farms is a 600-acre mixed-use development by Boyle Investment Company off Lewisburg Pike on Franklin's southern edge, at the I-65 / Peytonsville Road (Goose Creek Bypass) interchange. At full buildout it is planned for roughly 1,100 residential units alongside office and retail. It's positioned as a counterpart to Westhaven and Tollgate Village, with cottage and village homes from multiple builders across its residential sections (berryfarmstn.com; Boyle Investment Company; verify current pricing, which moves with each release).

Poplar Farms and other Franklin communities

Poplar Farms, off the Cool Springs / Brentwood corridor, is a Meritage Homes community of about 142 single-family homes anchored by a resort-style amenity center. Meritage plans there run on floor plans of about 1,500 to 3,000-plus square feet (Meritage Homes, 2026; confirm current releases and pricing). Franklin also carries a deep custom-home market around College Grove, where new construction can run well into the multi-millions.

Nolensville: the in-between market

Nolensville, in the county's northeast corner, has new construction going up across about 10 communities (nashvillehome.guru, 2026). Product runs from townhomes up through single-family homes in premium communities; we pull each builder's current price sheet.

Fairington

Fairington is a roughly 372-acre master-planned community by Southern Land Company — the same developer behind Westhaven. At completion it's planned for more than 700 homes, with about 160 acres of parks and open space, an amenity park with pool and fitness center, a village center with neighborhood retail, and programmed community events. Homes are designed and built by SLC Homes, and new phases continue to release (Southern Land Company / fairingtontn.com, 2026); ask us for the builder's current price sheet.

Bent Creek, Burberry Glen, and more

Other Nolensville communities include Bent Creek and Sherwood Green Estates, Burberry Glen and The Woods at Burberry Glen, plus Stonebrook, Lochridge (sold out; resales only), Silver Stream Farm, and Annecy — a mix of townhome and single-family product.

Spring Hill: the two-county market

Spring Hill straddles the Williamson–Maury county line, with a deep builder market on both sides of it. Greater Nashville REALTORS' 2026 outlook described a steadier, more balanced Middle Tennessee market overall, with rising inventory giving buyers more choice.

June Lake

June Lake is a large new master-plan at the Spring Hill / Thompson's Station line near the I-65 June Lake interchange, envisioned as a walkable '20-minute city' with a town center, dining, shopping, greenways, and a lake; at full buildout the development is planned for thousands of homes alongside commercial space. Signature Homes was selected as the primary Phase I residential builder and received city approval to deliver 400 single-family homes and townhomes plus an amenity center with pool, gym, and clubhouse (Southeast Venture; City Now Next; Williamson Source). Floor plans include three- and four-bedroom designs with two-car garages and included kitchen appliances.

The broader Spring Hill builder market

Beyond June Lake, Spring Hill has dozens of new-construction communities, with national and regional builders releasing inventory and quick-move-in homes year-round. Because Spring Hill spans two counties, confirm which side of the Williamson–Maury line a community sits on — it affects property taxes, school zoning, and city services.

Thompson's Station: the fast-growing middle ground

Thompson's Station, just south of Franklin, has grown quickly and offers larger lots and newer master-plans, with newer-construction prices spanning roughly the high-$400s for attached product up into the $1 million-plus range for larger single-family plans (nashvillehome.guru, 2026).

Tollgate Village

Tollgate Village is a master-planned, mixed-use community that has been developing since 2006, with a pool, clubhouse, fitness center, tennis courts, walking trails, playground, and dog park. Builders in and around the community include Regent Homes (whose Town Center offers townhomes and condos), Tennessee Valley Homes, and Lennar. Buyers in the broader Thompson's Station area also work with builders such as Drees Homes and Dream Finders Homes in nearby communities (Regent Homes / nashvillesmls.com / nashvillehome.guru, 2026; confirm which builder is active in a given section before you tour).

Fairhaven, Canterbury, and Parsons Valley

Fairhaven offers larger floor plans and generous lots; Canterbury is a European-inspired neighborhood with wide sidewalks and lamp-lit streets; and Parsons Valley is one of Thompson's Station's newer communities, with solar included on some homes (nashvillehome.guru, 2026; confirm current pricing per release). Several buyers also work directly with custom builders such as Barlow Builders and Partners In Building in this area.

Price bands and lot premiums: what to actually budget

Two costs surprise new-construction buyers most: lot premiums and the gap between the advertised base price and what you'll actually pay.

• •Entry points differ by city and by builder; we pull each builder's current price sheet, with the date, for the cities you're weighing.
• •Lot premiums are real money: corner lots, cul-de-sacs, larger or wooded homesites, water/golf views, and walk-out basements can add from a few thousand to tens of thousands on top of base price.
• •Base price is rarely final price — design-center upgrades and structural options push the finished number well above the brochure. Budget for the all-in price.
• •Incentives shift the math. In 2026, builders often move on closing-cost credits and rate buydowns through preferred lenders rather than headline price cuts; our team tracks current concessions and days-on-market by community.
• •VA buyers: many of these communities work well with VA financing, so ask about VA-eligible lenders and any community-specific requirements before you tour.

Why your own agent matters when you buy from a builder

This is the single most important thing to understand about new construction: the agent in the model home works for the builder. A good on-site agent is a real asset, but their fiduciary duty runs to the seller, not to you. When you walk in unrepresented, you're negotiating against a professional whose income and loyalty are tied to the builder's bottom line.

Having your own agent puts a licensed advocate on your side of the table — at little or no cost to you; how it is paid is settled per offer, in writing. Here's where independent representation earns its keep:

• •Negotiating the full deal — not just price, but lot premium, included upgrades, closing-cost credits, and rate buydowns, where builders are often more flexible than on sticker price.
• •Reading the builder's contract — written to protect the builder — including timeline, change-order, financing-contingency, and warranty terms.
• •Independent inspections at the right milestones (pre-drywall and final walkthrough) and a punch list the builder is held to before closing.
• •A clear-eyed read on lot selection, floor-plan resale appeal, and how later phases may affect your homesite.
• •Comparing across builders and communities countywide — not just the model home you happened to walk into first.

One practical note: most builders ask that your agent accompany or register you on your first visit for representation to apply, so loop us in before you tour. We work as a partner to the on-site sales teams — they build great homes, and our job is to make sure your side of the transaction is fully represented.

2026 market and rate outlook (from named forecasters)

No one can guarantee where rates or prices go, and our team doesn't make predictions. For planning, here is where things stood in mid-2026: Freddie Mac's Primary Mortgage Market Survey put the average 30-year fixed rate around 6.5% in late June 2026 (Freddie Mac PMMS, June 25, 2026). Looking ahead, Fannie Mae's mid-2026 forecast had the 30-year rate holding near 6.4% through year-end (Fannie Mae Housing Forecast, June 2026); the Mortgage Bankers Association projected 30-year rates averaging about 6.5% across 2026–2028 (MBA Mortgage Finance Forecast, 2026); and the National Association of REALTORS projected about 6.0% for 2026 (NAR, 2026). Earlier-2026 forecasts had been more optimistic, so treat the current consensus — roughly 6.0% to 6.5% — as a range, not a guarantee, which is exactly why builder rate buydowns are worth negotiating. Locally, Greater Nashville REALTORS' 2026 outlook described a more balanced Middle Tennessee market with rising inventory (active listings up sharply year over year) and steadier prices.

Frequently asked questions

How do I find an entry point into Williamson County new construction in 2026?

Compare townhomes and smaller single-family plans across Spring Hill, Nolensville, and Thompson's Station, and ask for each builder's current, dated price sheet. Confirm current releases, because builder pricing and incentives change with each phase.

Does it cost extra to use my own agent on a new build?

On a new-construction purchase it is little or no cost to you; how it is paid is settled per offer, in writing. The catch is timing — many builders require your agent to register or accompany you on your first visit, so contact us before you tour.

Which builders are active in Williamson County?

It varies by community. Examples include Signature Homes at June Lake (Spring Hill / Thompson's Station); Regent Homes, Tennessee Valley Homes, and Lennar in and around Tollgate Village (Thompson's Station); Ford Classic Homes, Legend Homes, SLC Homes, Stonegate, and Zurich at Westhaven (Franklin); SLC Homes at Fairington (Nolensville); and Meritage Homes at Poplar Farms (Franklin). We can match builders to your budget and must-haves countywide.

How are lot premiums and upgrades handled?

Lot premiums (corner, cul-de-sac, view, larger, or walk-out homesites) and design-center upgrades are added on top of the base price and can move the all-in number significantly. Budget for the finished price, not the model-home base, and have your agent help you prioritize upgrades that hold value.
