New Construction Luxury Homes in Southlake 2026

By Kim Assaad and The Assaad Group at Compass

TL;DR: Southlake new construction in 2026 is a constrained, premium market. Available teardown and infill lots in the core school zones — Carroll, Walnut Grove, Old Union, Johnson — are trading at $700,000 to $2 million before any vertical work begins, and finished new homes are clearing $3 million to $12 million depending on lot, builder, and feature program. Active luxury builders include Sandlin, Calais Custom Homes, Sharif & Munir, Drees Custom Homes, Toll Brothers (in Carillon), and a small group of boutique custom builders. The defining subdivisions are Carillon Parc, Westmont Estates, Estes Park, and the established custom-home corridors of Continental Boulevard, Shady Oaks Drive, and Burney Lane. This guide breaks down the actual builders, neighborhoods, price tiers, and timelines you will encounter as a luxury buyer in Southlake's 2026 new-construction market.

---

Southlake has been the premier luxury suburb of Dallas-Fort Worth for more than two decades, and 2026 is the year the new-construction segment has fully reasserted itself after the supply contraction of 2022 and 2023. Land is back. Builders are back. Buyers are back — and the buyer pool now includes a meaningful share of relocations from California, New York, Illinois, and the Pacific Northwest, alongside the in-state moves from Dallas, Plano, and Frisco that have always defined the city's growth.

What has changed since the last new-construction cycle is the scarcity of buildable lots in the core school zones, the substantial step up in expected feature programs (smart home, indoor-outdoor living, primary-suite design, energy efficiency), and the price floor on finished homes, which has pushed past $3 million in the established custom corridors and approaches $5 million as the new starting point for serious trophy construction. This is what the 2026 luxury new-construction landscape actually looks like on the ground.

Why Southlake — A Quick Refresher on the Demand Story

Southlake's draw comes from a stack of factors that no other DFW suburb fully replicates.

Carroll Independent School District is the foundation. Carroll consistently ranks among the top public school districts in Texas and the nation; Carroll Senior High School sits in the upper percentiles of national high-school rankings, and the elementary and middle schools (Old Union, Walnut Grove, Carroll, Johnson, Eubanks) all operate at high academic and athletic standards. Families relocating from out of state explicitly target Carroll; the district has been the single largest factor pulling private-school families in coastal cities into a public-school option in DFW.

Southlake Town Square — the master-planned mixed-use center at the heart of the city — combines retail, dining, a multiplex cinema, a hotel (the Hilton), and outdoor public space in a walkable layout that gives Southlake an actual downtown. Town Square is a daily-life amenity for residents and a clear differentiator versus comparable suburbs.

Corporate proximity. Southlake sits within 15 minutes of three of the largest corporate campuses in DFW: the Charles Schwab headquarters in Westlake (immediately adjacent to Southlake), the Sabre headquarters in Solana, and the Fidelity campus in Westlake. JPMorgan Chase, Wells Fargo, and other major financial-services employers have meaningful presences in the broader DFW corridor that puts Southlake directly in commute range. The new Apple Park-North expansion in Plano and the McKinney corporate corridor are 25 to 35 minutes east. DFW International Airport is 15 minutes south, which makes Southlake the highest-frequency-traveler suburb in the Metroplex.

Lifestyle infrastructure. The Marq Southlake (the city's recreation center), Bicentennial Park, the Bob Jones Park trail system, multiple country clubs (Timarron, Vaquero, the Trophy Club), and one of the strongest youth-sports infrastructures in the state round out the lifestyle picture. Southlake households tend to have multiple school-age children and the city is deliberately built for that demographic.

These factors combine to keep new-construction demand persistent across cycles. Even in the slower national real estate market of late 2024 and early 2025, finished new homes in Carroll-zoned blocks continued to clear within 30 to 90 days of completion at premiums to comparable existing inventory.

The Buildable-Lot Reality in 2026

The single most important fact about Southlake new construction in 2026 is lot scarcity. The city has effectively built out the large undeveloped tracts that fed the 1990s and 2000s new-home boom. New-construction inventory now comes from three sources, in roughly this order of volume:

1. Teardown and rebuild on existing lots in Carroll-zoned subdivisions. The dominant volume source. A 1990s 4,000-square-foot home on a half-acre lot in a desirable Carroll-zoned subdivision is purchased for $1.2 million to $2 million, demolished, and replaced with a new 6,500- to 9,500-square-foot custom home. Total project cost (land + demo + build + finish) typically runs $4 million to $8 million. The buyer is usually a relocating family or an established Southlake household stepping up.

2. Infill custom homes on remaining premium lots. A small but steady supply of buildable lots — roughly 1 to 5 acres — exists along Continental Boulevard, Shady Oaks Drive, Burney Lane, Lake Drive, and the rural-cluster blocks east of White Chapel Boulevard. Lots in this category are trading at $1.5 million to $4 million unimproved, with the higher end reflecting larger acreage and frontage. Finished homes built on these lots routinely clear $6 million to $12 million.

3. New master-planned communities. A small number of active master-planned developments are delivering completed inventory. The most significant are described below. Together they account for the majority of fully-finished new homes in the $3 million to $6 million tier in 2026.

The practical upshot: a buyer entering the Southlake new-construction market should expect to either (a) select a finished home from one of the active master-planned communities, (b) buy a finished home on the secondary market from a builder who completed it on spec, or (c) commit to a 14- to 24-month lot-acquisition-plus-build timeline through a custom builder. Each path has its own price band and risk profile.

The Subdivisions That Define Luxury New Construction

Carillon Parc

Carillon Parc — the master-planned community along Carillon Parkway in the western section of Southlake — is the largest active luxury new-construction development in the city. The community is built around a French-inspired architectural standard (inspired by Carillon, the Toll Brothers parent project nearby), with an extensive amenity package that includes a private clubhouse, swimming and tennis facilities, a community park, walking trails, and access to Bob Jones Park and Lake Grapevine.

Builders active in Carillon Parc include Toll Brothers (the master developer), Calais Custom Homes, and a curated set of custom builders working within the community's design review standards. Lot sizes range from one-third to over one acre; finished home pricing ranges from approximately $2.5 million for the smaller production-builder homes to $8 million-plus for the largest custom builds on the premium lots.

The community's defining feature is its architectural cohesion — the houses, while individually designed, share a French country and transitional vocabulary that creates a coherent neighborhood feel. For buyers who want the master-planned amenity package and a clearly defined architectural standard, Carillon Parc is the leading choice in 2026.

Westmont Estates

Westmont Estates, on the western side of Southlake, is a smaller, more exclusive enclave of custom homes on substantial lots. The community has historically attracted long-tenure Southlake families and out-of-state executive relocations. Finished home pricing ranges from approximately $3 million to $7 million, with the largest estate-tier homes trading higher when they reach the market.

Inventory in Westmont moves slowly — often privately, frequently through agent relationships before public listing. Active building in 2026 is concentrated on a handful of remaining premium lots and on teardown-rebuild projects on existing homesites.

Estes Park

Estes Park, accessed off Continental Boulevard, is a gated community of larger custom homes on lots of one-half to one-plus acres. The community attracts buyers who want a guarded entry, a stronger sense of seclusion, and homes in the $3 million to $6 million tier. New construction in Estes Park is primarily teardown-rebuild on the original 1990s/2000s housing stock.

The Continental Boulevard / Shady Oaks Corridor

The streets along Continental Boulevard, Shady Oaks Drive, and Burney Lane form the historical luxury custom-home backbone of Southlake. Lot sizes in this corridor range from one-half acre to over five acres, and the properties along the western and northern edges back up to greenbelts, Lake Grapevine, or open agricultural land. This is the corridor where the largest custom homes in Southlake — 10,000-plus square feet, on multi-acre lots, with extensive outdoor amenity programs — are concentrated.

Available lots in this corridor are extremely scarce in 2026. Teardown-rebuilds on existing 1990s homes are the dominant volume source. Finished home pricing in the corridor ranges from $5 million for the smaller new builds to $15 million-plus for the largest estate-tier construction. A meaningful share of activity in this corridor never appears on the public MLS.

Vaquero

Vaquero — the Tom Fazio-designed gated golf-and-residential community immediately west of Southlake, technically in Westlake but functionally part of the broader Carroll-zoned luxury market — anchors the high end of the regional new-construction market. New homes in Vaquero range from approximately $5 million to $25 million. The community's design standards are unusually strict, and new construction is a multi-year process for most owners. Vaquero is mentioned alongside Southlake new construction because Vaquero buyers and Southlake buyers overlap substantially, and the two markets shape each other.

Timarron

Timarron, on the eastern side of Southlake, is the city's older established master-planned community, anchored by Timarron Country Club. New construction in Timarron is primarily teardown-rebuild on the community's original 1990s housing stock, with finished home pricing ranging from $2.5 million to $5 million depending on lot, golf-course frontage, and home program. Timarron remains a strong family-stage choice for buyers who want country-club lifestyle and proximity to Old Union Elementary and Carroll Middle.

The Active Luxury Builders in Southlake

The luxury custom-builder roster in Southlake is well-established. The names that come up consistently in 2026 transactions:

Sandlin Homes. Long-tenure DFW custom builder with a substantial Southlake presence. Strong reputation for build quality, project management, and post-completion service. Active in the $3 million to $8 million custom range.

Calais Custom Homes. A premier DFW custom builder known for distinctive transitional and modern-traditional architecture. Active in Carillon Parc and the Continental Boulevard / Shady Oaks corridor. Project range typically $4 million to $12 million.

Sharif & Munir. Among the most prominent luxury custom builders in DFW, with a deep portfolio of high-end estate work in Southlake, Westlake, Highland Park, and Preston Hollow. Active at the upper end of the Southlake custom market — typically $5 million to $20 million-plus for the largest estate builds.

Drees Custom Homes. Active in master-planned communities and for production-luxury work in the $2 million to $4 million tier. Strong reputation for design flexibility within a defined floor-plan library.

Toll Brothers. The master developer of Carillon Parc and other planned communities; their City Living and Hampton-collection product is the production-luxury anchor in Southlake's master-planned segment.

Britton Homes. Established North Texas builder active in production-luxury and semi-custom work in the $2 million to $4 million range.

Boutique custom builders. A rotating set of smaller custom builders — Boutwell Custom Homes, Heritage Custom Homes, Luxe Custom Homes, and a handful of architect-led design-build operations — that take on a small number of projects per year, typically in the $4 million to $10 million range. These builders are often the right answer for buyers who want one-of-one architecture and are willing to commit to a longer timeline.

A practical buyer note: in 2026, the strongest custom builders are running 12- to 18-month waitlists for new client engagements. Buyers planning a custom build should engage their builder before they have closed on a lot — the lot-selection process and the architectural design process are best run in parallel, and the builder's relationships with land brokers and recent comparable transactions are an information asset.

What Finished Homes Actually Cost in 2026

The price-by-tier breakdown for Southlake new construction in 2026:

Tier	Price Range	What It Buys	Typical Path
Production luxury	$2.0M – $3.5M	4,500–6,500 sf in a master-planned community on a sub-half-acre lot	Toll Brothers, Drees, Britton in Carillon Parc and similar; available as finished spec
Mid custom	$3.5M – $5.5M	6,000–8,000 sf on a half- to one-acre lot in a Carroll-zoned subdivision	Sandlin, Calais, smaller custom builders; teardown-rebuild or master-planned premium
Upper custom	$5.5M – $9M	7,500–10,000 sf on a one-plus-acre lot, premium block	Calais, Sharif & Munir, boutique builders; Continental/Shady Oaks corridor or Estes Park
Estate	$9M – $20M+	10,000+ sf on multi-acre lots, often with extended outdoor programs	Sharif & Munir and architect-led custom; trophy lots in the Continental corridor or Vaquero

Per-square-foot pricing in 2026 runs approximately:

• Production-luxury finished spec: $475 to $625 per square foot
• Mid custom: $625 to $850 per square foot
• Upper custom: $850 to $1,100 per square foot
• Estate-tier custom: $1,100 to $1,800 per square foot

These numbers reflect finished home pricing inclusive of land. Land cost as a share of total project varies meaningfully — production-luxury homes carry land at 25 to 35 percent of total cost, while estate-tier projects on premium lots can carry land at 35 to 50 percent.

Build Timelines — What 2026 Looks Like

Construction timelines in Southlake have meaningfully extended versus the pre-2022 baseline.

Production-luxury finished spec. From contract to closing, typically 30 to 90 days because the home is already built or near completion. This is the fastest path into a new home in Southlake.

Production-luxury new build (master-planned community, choose-your-finishes). From contract to closing, typically 9 to 14 months. The builder controls the construction schedule and the buyer's main decisions are around finishes and options.

Semi-custom on the builder's floor plan. From contract to closing, typically 12 to 18 months. The buyer modifies a builder's existing plan; lot, finishes, and some structural elements are buyer-selected.

Full custom from architectural design. From buyer engagement to move-in, typically 22 to 36 months. The buyer engages an architect (six to nine months for design and permitting), then the builder (two to three months for pre-construction), then construction (14 to 22 months for an upper-custom or estate-tier home).

The custom timeline has expanded versus the pre-2022 norm because of permit processing, materials lead times, and finish-material backlogs (custom millwork, stone, and high-end appliance lead times have all extended). Buyers who want to be in their new home by a specific date — most commonly aligned with a school year — should commit to their lot and builder no later than 24 months ahead.

The Feature Program in 2026 — What Luxury Buyers Expect

Luxury new construction in Southlake is being built to a meaningfully higher feature standard than even five years ago. Buyers entering the market in 2026 expect, as a baseline:

Indoor-outdoor living. Multi-slide or bi-fold glass doors spanning 16 to 24 feet, opening from the main living area onto a covered outdoor living space with full outdoor kitchen, fireplace, and resort-style pool. We covered this in detail in Top 5 Home Features DFW Luxury Buyers Want in 2026; the indoor-outdoor program is non-negotiable in any home above $3 million in Southlake.

Primary suite retreats. A primary suite that functions as a small house — bedroom, sitting area, spa-quality bathroom, oversized walk-in closet with island, and frequently a dedicated coffee bar or morning kitchen.

Smart home automation. Whole-home Control4 or Crestron, with lighting, climate, audio, video, security, and shade control all unified. Pre-wired Ethernet to every room, enterprise-grade Wi-Fi, and EV charging infrastructure (ideally Level 2) in the garage.

Multiple home offices. Dual-office is the new standard at $4 million-plus — one for each working partner, both with sound insulation, professional video-call lighting, and proper desk and shelving builds.

Casitas or guest suites. Detached or semi-detached guest quarters, with their own bedroom, bathroom, kitchenette, and entrance, are showing up in upper-custom and estate-tier construction at meaningful frequency. Multi-generational living, returning adult children, and out-of-state visiting family are all driving demand.

Energy efficiency. Spray foam insulation, tankless water heaters, high-SEER HVAC, low-E windows, and solar-ready roofing are the baseline. A subset of buyers are specifying full solar arrays and battery storage at the time of build.

Substantial outdoor program. Pool, spa, outdoor kitchen, sport court, putting green, dedicated fire pit area — the trophy-tier outdoor program in Southlake new construction has expanded substantially in 2026.

How To Buy New Construction in Southlake — A Practical Process

The standard process I run with new-construction buyers in Southlake:

Step 1: Define the path. Finished spec, master-planned new build, semi-custom, or full custom. Each path has different timelines, pricing, and decision loads. The right answer depends on your move-in date, your customization appetite, and your budget.

Step 2: Define the geography. Carroll-zoned only, Carroll plus adjacent zones (Northwest ISD, Grapevine-Colleyville ISD), or open across Southlake-Westlake-Trophy Club. School zoning is the dominant constraint for most buyers and should be set first.

Step 3: Tour the active inventory and the active builders. Walk the active master-planned community model homes (Carillon Parc, Estes Park, Westmont) to calibrate on production-luxury feel and pricing. Tour completed projects from the custom builders you are considering. The build quality and design vocabulary differences between Sandlin, Calais, Sharif & Munir, and the boutique builders are real and worth experiencing first-hand.

Step 4: Engage the builder before the lot. Counterintuitive but correct in the current market. Your custom builder's land relationships, awareness of off-market lot opportunities, and understanding of buildable conditions on specific lots will shape your lot decision.

Step 5: Acquire the lot. Through MLS, off-market relationship, or builder-controlled inventory. Lot due diligence — soil tests, utilities, easements, setbacks, flood elevation, tree-protection ordinances — is more involved in Southlake than in less mature markets and should not be shortcut.

Step 6: Architecture and permitting. For full custom, six to nine months. For semi-custom, two to three months. The City of Southlake's permitting process is professional and predictable but not fast.

Step 7: Construction. 14 to 22 months for an upper-custom or estate build, with bi-weekly site meetings and a clear payment-draw schedule.

Step 8: Walk-throughs and closing. Pre-final walkthrough at the 95-percent-complete mark, final walkthrough before closing, and a 12-month post-close warranty period during which the builder addresses any issues that emerge as the home settles.

The process is not difficult but it is long, and the difference between a successful new-construction project and a frustrating one is almost always upstream — in the builder selection, lot choice, and architectural program — not in the construction itself.

Frequently Asked Questions

What is the cheapest entry point into a new-construction luxury home in Southlake in 2026? A finished production-luxury spec home in Carillon Parc or a similar master-planned community, in the $2.5 million to $3.0 million range. These homes typically deliver 4,500 to 5,500 square feet on lots under half an acre, with high-quality finishes, full builder warranty, and a 30- to 90-day path from contract to closing.

How much does a custom home cost to build in Southlake? Mid custom (6,000 to 8,000 sf) runs $3.5 million to $5.5 million all-in. Upper custom (7,500 to 10,000 sf) runs $5.5 million to $9 million. Estate-tier (10,000-plus sf on multi-acre) runs $9 million to $20 million-plus. Per-square-foot pricing scales from $625 in the mid-custom tier to $1,800 at the estate-tier ceiling.

Is it cheaper to build new or buy existing in Southlake? In 2026, finished new construction trades at a 10 to 25 percent premium per square foot versus comparable existing inventory in Southlake. The premium is justified for buyers who want current feature programs, builder warranty, and the ability to customize. Buyers willing to renovate existing inventory can land in the same neighborhoods at meaningfully lower per-square-foot pricing if they have the renovation appetite.

Are buildable lots still available in Southlake? Yes, but scarcity is acute. Available lots in 2026 trade at $1.5 million to $4 million unimproved for premium blocks, and a meaningful share of activity is teardown-rebuild on existing lots. Buyers should be working with both their custom builder and their agent to identify off-market lot opportunities.

What is the build timeline? 9 to 14 months for production-luxury new build. 12 to 18 months for semi-custom. 22 to 36 months for full custom. Buyers who need to be in by a specific school-year start date should commit 24 months ahead.

Which Southlake builders are best for $3-5M custom homes? Sandlin, Drees Custom Homes, and Calais Custom Homes are the most active builders in this tier. Each has a clear design vocabulary and a strong project-management practice. Touring their completed work is the right way to calibrate the choice.

Which Southlake builders are best for $5-10M estate-tier? Calais, Sharif & Munir, and a small set of architect-led boutique builders. Sharif & Munir is the consistent presence at the top of the Southlake custom market.

What are the top neighborhoods for new construction in Southlake? Carillon Parc (master-planned, Toll Brothers and Calais), Westmont Estates (custom, exclusive), Estes Park (gated custom), and the Continental Boulevard / Shady Oaks / Burney Lane corridor (custom, premium lots). Vaquero in adjacent Westlake is the regional trophy market and overlaps the Southlake buyer pool.

Is Carroll ISD really worth the premium? For families with school-age children, yes. Carroll consistently ranks among the top public school districts in Texas; Carroll Senior High School is in the upper tier of national public-school rankings. The price premium for Carroll-zoned addresses versus comparable adjacent zones is real and reflects the school value.

What about Westlake or Trophy Club? Both are strong adjacent markets with their own school districts (Westlake's Carroll-shared and adjacent Westlake Academy, Northwest ISD for Trophy Club). For buyers who want the broader luxury new-construction market and are flexible on school zoning, Vaquero (Westlake) and the new-construction blocks in Trophy Club are worth tour. For pure Carroll-zone access, Southlake remains the choice.
