A shiny new spec mansion on Strait Lane in Preston Hollow is taking a big swing at the Dallas luxury market with a $25 million price tag. The three-story, California-transitional estate sits on roughly 2.2 acres along Bachman Creek and could end up as the priciest newly built house in Dallas this season. Built on spec by local firm Hadley & Bess, the property leans hard into high-end amenities and a 10-car garage aimed squarely at trophy-home buyers, signaling a fresh push into ultra-luxury new construction in North Texas.
According to the listing from Allie Beth Allman & Associates, the home spans about 16,600 square feet, with seven bedrooms and 11 bathrooms on 2.22 acres. The ask is $24,999,900, which works out to roughly $1,500 per square foot. The listing also shows a 10-car garage, and Susie Thompson is noted as the selling agent on the MLS entry.
Inside the Highclaire
On paper, the amenities read more like a private resort than a single-family home. Builder materials describe a lower-level wine vault, a golf simulator room, a three-tier theater and a wellness retreat, all tied together with elevator service. Outside, there is a screened loggia, outdoor kitchen, negative-edge pool and multiple terraces, according to Hadley & Bess. The firm brands this version of the project as "The Highclaire," with an emphasis on indoor-outdoor living and a concrete-and-steel structure aimed at durability and privacy.
How the deal came together
Founders Abby and Stephen Simpton of Hadley & Bess turned the Strait Lane parcel into their largest build to date after acquiring the roughly 2.2-acre site in 2021. Abby Simpton told The Real Deal, "Once the 2.2 acres went on the market for $3 million, we grabbed it up." According to that reporting, the developer first floated the home to buyers in 2023 for $18.5 million while it was still under construction.
Where it lands in a heated luxury market
The Strait Lane estate drops into an already crowded field of ultra-high-end homes across Dallas-Fort Worth that routinely top statewide price charts. The Dallas Morning News ranked the property among the region’s most expensive listings, pointing to its sheer size and its creekside setting in Old Preston Hollow. For builders and agents, the price on this one is a live-fire test of how far buyers will go for brand-new, turnkey estates inside the city’s most coveted blocks.
Listing records on Compass and affiliated MLS feeds show the current entry went active in early March 2026 and remains publicly marked as available. If the home lands a buyer near ask, it would set a lofty benchmark for newly built product in Dallas and highlight just how much of a premium buyers are willing to pay for large, private parcels inside the Loop. Full photos and detailed specifications are available through the MLS listing referenced above.
