Oak Hill Phase 3

Oak Hill Phase 3 is an early-stage single-family expansion in Gallatin — a proposed 33 lots on roughly 16.1 acres, sitting south of SR 31E and west of Roundtree Drive. As of mid-2026 it appears on the City of Gallatin's development tracker at the recent-preliminary-approval stage, which means the layout has cleared an initial review but the project is not yet built or selling. No builder has been announced and no pricing has been published. This page is the honest read on what is actually known today, and we keep it current as the city's tracker and the builder picture firm up.

Where it sits

The site is on the south side of SR 31E and just west of Roundtree Drive, which places it in an already-established corner of Gallatin rather than out on raw acreage. SR 31E is the main artery running through this part of Sumner County, so the everyday drive into the rest of the area follows a corridor that already exists — not a road that has to be built first. Gallatin sits at the northeast end of Sumner County, near Old Hickory Lake, and Phase 3, as the name suggests, slots into a neighborhood area that is partly there already.

The homes here

The record is thin on purpose, because the project is early. Oak Hill Phase 3 is platted for single-family homes — 33 lots across about 16.1 acres. Lot sizes, floor plans, square footage, the builder, and the feature list have not been published yet, and we are not going to invent any of it. When a builder is named and the first plans and prices are released, this is exactly where they will land — and if you want to be on the list the day that happens, we can flag it for you ahead of the public listings.

Who it fits

On paper, a small expansion phase like this tends to suit a buyer who wants a brand-new single-family home inside an area that is already settled, rather than the raw edge of a large new subdivision — new construction with established surroundings nearby and a short commute back along an existing road. Until plans and pricing are out, that is the honest extent of what the lifestyle fit looks like. We would rather tell you it is early than dress it up.

What to verify before you buy here

• Project stage and timeline — it sits at recent preliminary approval on the City of Gallatin development tracker, not under construction. Confirm where it actually stands before you build any plans around it, since preliminary approval is a step, not a guaranteed delivery date.
• Builder and what is included — no builder has been named yet. Once one is, get the standard-versus-upgrade list in writing, because the base price and the model home are rarely the same house.
• Pricing and lot premiums — nothing is builder-published yet. When prices come out, confirm them directly and ask which lots carry premiums.
• The plat and your specific lot — lot sizes are not published; review the recorded plat for setbacks, easements, drainage, and any HOA or grading details before you commit to a particular lot.
• School zoning — confirm the current attendance zoning for the exact address with Sumner County Schools yourself, since lines can be redrawn as new sections deliver.
