New construction in Southlake is currently listing for close to double what a resale home commands citywide, and it's sitting on the market nearly three times as long. As of late September 2026, Redfin's tracking shows 34 new-construction homes for sale in Southlake at a median list price of $2.21 million, with those homes averaging 74 days on market and drawing four offers apiece. Compare that to March 2026, when the median resale home in Southlake closed at $1.3 million after 25 days on market with two offers.
That gap should not exist if new construction were simply the more desirable product at a higher price. A buyer walking into a $2 million new build in Southlake reasonably expects speed and certainty to come with the premium. Instead, the math says the opposite is happening. The premium is real. The speed isn't.
The Days-on-Market Number That Doesn't Add Up
Two facts sitting next to each other explain why comparing Southlake listings by price alone leads buyers astray. New construction costs roughly 70 percent more than the citywide resale median, and it takes roughly three times as long to sell. If new construction buyers were simply paying for scarcity and getting a faster transaction in return, days on market would compress as price rises. It's doing the reverse.
The most likely explanation isn't that new construction is undesirable. It's that "new construction in Southlake" describes several different products stacked into one median, and the buyer pool for each is smaller and more particular than the citywide resale pool. A $2.21 million median blends walkable, HOA-maintained communities built for convenience with cul-de-sac estate lots built for privacy and acreage. Those are different purchases aimed at different people, and each waits longer for the right buyer to show up than a resale home in an established neighborhood does.
Why the Lots Got This Small
Southlake is not building the way it was ten years ago, and the reason is straightforward geography. The city spans about 22.5 square miles and is already close to fully developed. According to the city's own planning department, fewer than 800 buildable residential lots remain, and annual building permits have fallen from 180 in 2020 to roughly 65 in 2025. At that pace, new construction is expected to effectively stop by 2029 or 2030.
That scarcity changes what builders can offer. A decade ago, a Southlake builder could plat a subdivision on raw acreage and sell half-acre-plus lots as the default. Today, every new project is squeezing a finished product out of whatever parcel is left, which means the lot itself becomes the scarce ingredient rather than the finish-out. Some builders are protecting acreage on the last available cul-de-sacs. Others are trading lot size for shared amenities and low-maintenance living. Both show up in the same "new construction" bucket on a portal search, and the median price hides which one you're actually looking at.
What a Smaller Lot Actually Looks Like, Development by Development
Southlake's own development data shows how wide the gap has become between legacy estate subdivisions and what's being built now.
| Community | Average Lot Size | Type |
|---|---|---|
| Harbor Oaks | 116,437 sq ft | Established estate subdivision |
| Huse Homeplace | 120,032 sq ft | Established estate subdivision |
| Hudson Bay Estates | 115,231 sq ft | Established estate subdivision |
| Lakewood Ridge Addition | 88,367 sq ft | Established estate subdivision |
| Linmar Estates | 25,000 to 54,000 sq ft | New, Calais Custom Homes, 10 lots on 10.8 acres |
| The Estates at Crescent Heights | Roughly 43,560 sq ft (1+ acre) | New, Calais Custom Homes, four lots across from Bicentennial Park |
| The Metairie | Roughly 22,500 sq ft average | New, Hawkins-Welwood Homes, 56 homes on 29 acres, HOA-maintained lawns |
That last figure is worth sitting with. The Metairie's own marketing describes it as a 29-acre community offering 56 homes with front lawns maintained by the HOA, built for buyers who want low-maintenance living over acreage. Divide 29 acres across 56 lots and the average comes out to roughly half an acre, less than half the footprint of Harbor Oaks or Hudson Bay Estates a few miles away.
Carillon Parc sits at the far end of that spectrum. It's a 42-acre mixed-use development built around a boutique hotel, a public library, chef-driven dining, and a landscaped central plaza, designed as a walkable district rather than a collection of house lots. Buying into Carillon Parc is not a smaller version of buying into Harbor Oaks. It's a different real estate product entirely, priced against convenience and proximity rather than against square footage of dirt.
Meanwhile, the Calais Custom Homes projects, Linmar Estates and The Estates at Crescent Heights, are doing the opposite. Each is a small, cul-de-sac-style enclave built specifically to preserve something closer to a full acre per lot, on some of the last parcels in the city where that's still possible. A third Calais project, The Oaks at Southlake, followed the same cul-de-sac, rural-feel template on 11 lots; infrastructure work began in January 2026, and lots were delivered for construction later that year, though the builder hasn't published an average lot size for it yet. One remaining lot at The Estates at Crescent Heights was recently priced at $1,295,000 before a home is even built on it, which gives a sense of what raw land alone is worth once it's this scarce.
The Two Southlakes You're Actually Comparing
Line these up and a pattern emerges. Southlake's new construction isn't one market moving in one direction. It's two markets that happen to share a zip code.
One is buying land while land still exists: cul-de-sac estate lots from builders like Calais Custom Homes, sized to compete with the city's legacy subdivisions rather than shrink from them. The buyer here is paying a premium for scarcity itself, for the fact that a half-acre-plus lot inside Southlake's city limits is a diminishing category with a hard end date attached to it.
The other is buying convenience: communities like The Metairie and Carillon Parc, where a smaller footprint and HOA-maintained landscaping are the selling point, not a compromise. That buyer isn't comparing against Hudson Bay Estates at all. They're comparing against the time and money it costs to maintain their current home and deciding the trade is worth it.
Both groups show up in the same $2.21 million median. Both wait longer than the citywide 25-day average because each is selling to a narrower, more specific buyer than a straightforward resale listing is. The premium isn't buying speed because speed was never really for sale. It's buying a specific kind of property that a smaller number of people are shopping for at any given moment.
What This Means If You're Pricing a Comparison
The practical fix is to stop comparing a listing to the citywide median and start comparing it to its actual peer group. If a new-construction listing sits on a half-acre or smaller lot, its fair comparison is The Metairie or a similar HOA-maintained community, not a legacy Southlake estate subdivision three times its size. If it sits on a full acre in a Calais-style cul-de-sac, its comparison is Harbor Oaks or Hudson Bay Estates, not the citywide new-construction median that's being pulled upward by walkable mixed-use pricing.
It also helps to read an individual listing's own trajectory rather than the citywide figure. In the 30 days ending in May 2026, roughly a quarter of active Southlake listings had already taken at least one price cut, up more than 12 points from a year earlier, while just over 32 percent were still closing above list price. Both things were true at the same time, in the same city, because the underlying properties weren't the same product. A listing that's been active 90 days with two price reductions is telling you something specific about that home. It has nothing to do with whether new construction, broadly, is in demand.
Frequently Asked Questions
How many buildable residential lots does Southlake have left? Fewer than 800, according to the city's planning department, with annual permits already down from 180 in 2020 to roughly 65 in 2025. At that trajectory, new construction is projected to effectively stop by 2029 or 2030.
Are all of Southlake's new communities built the same way? No. Projects like Linmar Estates and The Estates at Crescent Heights, along with The Oaks at Southlake now under construction, are built by Calais Custom Homes on a cul-de-sac, rural-feel template meant to preserve acreage on some of the city's last available parcels. Communities like The Metairie and Carillon Parc take the opposite approach, trading lot size for HOA-maintained landscaping or walkable amenities. Both count as "new construction" in market data, which is part of why that category's numbers look inconsistent from the outside.
If you're trying to figure out which side of that split a specific Southlake listing actually falls on, and what that means for how it should be priced against its real comparables, Sarah Gunnip can walk through the lot history and the neighborhood context with you before you make an offer.
