The numbers, up front

• •As of mid-2026, our team's survey identified 106 distinct new-construction communities across Williamson County, 84 of them actively selling, built by 88 named builders, across nine submarkets (Franklin, Brentwood, Nolensville, Thompson's Station, Fairview, College Grove, Spring Hill, Arrington, and unincorporated county sites).
• •In the four largest cities alone — Franklin, Brentwood, Nolensville, and Thompson's Station — 56 communities are actively selling (out of 74 tracked in any status), from at least 64 different named builders.

Why it matters for buyers

New construction in Williamson County isn't one product — it's dozens of builders competing across price points, from sub-$300K attached condos to eight-figure custom estates, often within a few miles of each other. That range means a buyer's real starting question isn't “is there new construction here” — there almost always is — it's which builder, community, and phase actually fits a given budget and timeline this month, since pricing and lot availability move fast as phases sell through. Growth is concentrated: Thompson's Station's population rose from 7,557 at the 2020 Census to an estimated 9,848 in 2026, and Nolensville is adding roughly 2.7% a year. We don't predict future prices or appreciation, and we don't rank neighborhoods by subjective “best” or “safe” — for school-zone questions, we point buyers to GreatSchools.org and the Tennessee Department of Education rather than offering our own opinion. What we do is confirm live pricing, current phase, and builder incentives directly before a buyer visits a community.

Methodology & sources

Community-level data (name, builder, city, starting price, status) is drawn from The Will Johnson Team's internal Williamson County new-construction dataset, built from builder websites (Drees, Turnberry, Celebration, Regent, Toll Brothers, Lennar, Beazer, John Wieland Homes/PulteGroup, Southern Land Company, and others), NewHomeSource.com, Redfin community pages, and the RealTracs-sourced aggregator nashvillehome.guru, cross-checked where possible against municipal planning documents. County median-price data is from RealTracs MLS via Grant Hammond's Market Pulse report (trailing six months, imported June 25, 2026). Population figures are Census Bureau Population Estimates Program data as compiled by worldpopulationreview.com (2026 estimates; 2020 figure is decennial Census). This is a snapshot, not a forecast — new-construction pricing and availability change frequently, and every figure should be reverified with the builder or listing before use in a transaction.
