If you've been searching for new construction in Southlake, you've probably noticed the same thing my clients keep noticing: there just isn't much left. A few years ago, builders like Toll Brothers were still delivering full subdivisions here. Now, with virtually no raw land remaining for large-scale development, the new-construction conversation in Southlake has quietly turned into something else entirely.

That shift matters if you're a move-up family planning a purchase in the next 6 to 12 months. You're no longer choosing between "new" and "resale" the way buyers in Flower Mound or Argyle still can. You're choosing between two very different paths: buy into one of the last small new-construction pockets, or buy a legacy home in an established neighborhood and remodel it into what you want.

Why Southlake Buyers Are Suddenly Choosing Between Two Different Paths

Southlake's housing stock skews older than people expect for a city with this kind of price point. The majority of high-end inventory was custom-built between 1998 and 2015, concentrated in foundational neighborhoods like Timarron and Monticello Estates. Timarron alone spans roughly 1,200 acres and 1,550 homes across 14 sub-neighborhoods dating back to 1993.

With land this scarce, buyers who want a newer feel are increasingly acquiring one of these legacy homes and modernizing it rather than waiting on a new build that may never come. At the same time, a small group of buyers is chasing the very last new-construction opportunities before they disappear.

Neither path is automatically better. It depends on how attached you are to a specific street or school boundary, how much of the process you want to control, and how you feel about carrying a renovation timeline versus a construction timeline.

The Last New-Construction Pockets Left in Southlake

If new construction is the priority, your options right now are narrow and mostly small, custom, single-builder communities rather than the multi-builder subdivisions Southlake had a decade ago:

• The Oaks at Southlake — Calais Custom Homes' newest project: 11 estate lots on a single private cul-de-sac off Highland Street, entirely within Carroll ISD. Infrastructure work started in January 2026, home construction is expected to begin around May 2026, and lots are scheduled for delivery in Q4 2026. Calais is accepting lot deposits now, but this is a reservation, not a move-in-ready home.
• Carillon Parc — A 42-acre mixed-use development at the corner of White Chapel Boulevard and State Highway 114, combining a boutique hotel, office space, retail, and residences. Five of its luxury homes were built as the St. Jude Dream Home Showplace, expected to open to the public in spring 2026 before going up for sale.
• Breeze Way at Carroll — A much smaller infill project bringing six single-family homes to a lot averaging about 22,435 square feet, recently approved by Southlake City Council.

None of these are large enough to move the needle on Southlake's overall inventory. If you want new construction here, you're competing for a genuinely limited number of lots, and the timeline runs on the builder's schedule, not yours. If your window is 6 to 12 months, a couple of these projects (Breeze Way, Carillon Parc) are close enough to finished product to be realistic. The Oaks is a longer runway, better suited to buyers planning further out.

What a Legacy Remodel Actually Costs in Timarron and Monticello

The other path, buying an existing home in Timarron or Monticello and remodeling it, has become the more common move simply because there's more inventory to work with. Here's what that actually costs in this market:

• Light-to-moderate remodels (cosmetic updates, kitchen and bath refreshes) generally run lower per square foot and are the fastest path to a "feels new" home without a full gut.
• Luxury gut renovations with structural changes, high-end finishes, and full systems updates typically run $200 to $350+ per square foot in the North Texas luxury tier. On a 2,500-square-foot renovation scope, that puts you at roughly $250,000 to $400,000+ if you're touching layout and mechanicals, not just finishes.
• Land itself isn't cheap either. If you did want to buy raw land and build from scratch nearby, undeveloped parcels near Southlake are averaging around $1.24 million to list, with land running close to $1.5 million per acre. That premium is a big part of why builders have stopped trying to assemble large tracts here.

The math that matters: a remodel lets you buy into an established street, an established lot size, and a known Carroll ISD attendance zone today, then spend the next 6 to 12 months turning a 2005 interior into something that lives like new construction. A new build gets you a genuinely new home, but on a much longer and less certain timeline, and often at a real land premium once you account for scarcity pricing.

How to Decide Between the Two

A few questions tend to clarify this fast for the families I work with:

How attached are you to a specific location? If your target is a particular street in Timarron, a particular Monticello lot, or proximity to a specific Carroll ISD elementary boundary, new construction may not exist there at all. A remodel is your only path to that address.

How much timeline risk can you absorb? The Oaks at Southlake won't have finished homes until well into 2026 at the earliest. If you need to be settled within a year, a remodel or one of the closer-to-finished projects like Carillon Parc fits better than a from-scratch new build.

Does the 2026 market actually favor waiting? Southlake inventory is up roughly 21% year over year, homes are averaging 63 to 68 days on market, and close to 44% of listings have taken a price reduction. That's a meaningfully more balanced market than Southlake has seen in years, which changes the leverage you have negotiating a legacy home purchase before you even start the remodel budget. I broke down what that inventory shift means for buyers and sellers in my Southlake market update.

Are you also selling your current home to fund this? Most move-up families in this position are financing the remodel or the new lot with proceeds from their current sale. That timing question, selling and buying (or building) at once, is its own puzzle. I walk through the contingency, bridge loan, and leaseback options here.

If you're still deciding whether Southlake is even the right target compared to a neighboring corridor, it's worth stepping back further. My Southlake vs. Flower Mound comparison covers price, lifestyle, and schools side by side.

Every family's numbers look different depending on the home they're selling, the remodel scope they want, and how the specific lot or subdivision they're eyeing is priced right now. That's exactly the kind of math I walk clients through before we write an offer or put a shovel in the ground.

Frequently Asked Questions

Is there any new construction left in Southlake, TX?

Yes, but it's limited to a small number of custom, low-lot-count communities rather than full subdivisions. The Oaks at Southlake (11 estate lots), Carillon Parc, and the small Breeze Way at Carroll infill project are the active new-construction options as of mid-2026, and none of them add meaningful inventory to the broader market.

Why is Southlake almost out of buildable land?

Southlake has been largely built out for years, and the large tracts that once supported subdivision-scale development, the kind builders like Toll Brothers used for communities like Southlake Meadows, are essentially gone. What's left is smaller infill parcels and a handful of larger custom lots, which is why new construction here now comes in communities of a dozen homes or fewer.

Is it cheaper to remodel a home in Timarron or Monticello than to build new?

Usually, yes, especially once you account for how expensive and scarce raw land has become in Southlake. A luxury gut renovation typically runs $200 to $350 or more per square foot, while land alone near Southlake is averaging close to $1.5 million per acre before you've spent a dollar on construction. Your specific number depends on your home's condition, scope, and finish level, which is where a contractor walkthrough and a real budget come in.

Does Carroll ISD zoning affect where I should buy in Southlake?

It can. Carroll ISD is planning a 2027-28 closure of Durham Intermediate School to move back to a traditional K-5 and 6-8 structure, and some elementary zones in the northern part of the district are nearing capacity. If a specific attendance boundary matters to your decision, verify current zoning directly with Carroll ISD before you commit to a lot or a home, since boundaries can shift as the district grows.

Does the 2026 buyer's market change whether I should remodel or build new?

It can tilt the math. With inventory up about 21% year over year and roughly 44% of Southlake listings taking a price cut, buyers have more room to negotiate on an existing home purchase than they did a year or two ago. That extra negotiating room can free up more of your budget for the remodel itself, which is worth factoring in before you decide between buying an existing home to update or waiting on one of the remaining new-construction lots.
