The pink-granite Towers at Williams Square, the office campus that frames the Mustangs of Las Colinas, has officially changed hands. A new joint venture led by Vanderbilt Office Properties, along with Hillwood Urban and TriPost Capital Partners, has acquired control of the 1.4 million-square-foot Class A complex, which also serves as Caterpillar Inc.'s global headquarters. The timing lines up with a broader wave of new amenities and corporate relocations that are quietly reshaping the Las Colinas office scene.
The Deal in Brief
Chicago-based Vanderbilt, Dallas-based Hillwood Urban, and New York-based TriPost teamed up as the buyer, and the new structure gives Vanderbilt and Hillwood a larger ownership stake than they previously held. Financial terms are under wraps, and the sale had not yet been logged in the county deed records at the time of reporting. Newmark represented the seller, while Beal Bank USA supplied the acquisition financing, according to Dallas News.
About the Campus
Spread across roughly 18 acres along Lake Carolyn, Williams Square is anchored by a 26-story central tower that is flanked by two 14-story high-rises, plus an additional smaller office building and ground-floor retail. The complex is organized around the Mustangs of Las Colinas sculpture and markets large 25,000-square-foot floorplates, covered parking, and an expanded amenity lineup, according to Williams Square.
The property last traded in 2015, when a joint venture that included Vanderbilt and Apollo Global Real Estate paid roughly $330 million. At the time, that price tag ranked among the largest suburban office sales in North Texas and helped set up subsequent capital improvements and leasing efforts, as detailed by D Magazine.
Tenant Mix, Renovations and Leasing
Vanderbilt's Casey Wold described the campus as "truly an iconic property," while Hillwood's Bill Brokaw credited its access, amenities, and walkable surroundings with fueling "significant and growing tenant activity." The complex is currently about 78 percent leased and wrapped up roughly $30 million in capital improvements in 2024, including upgrades to its top-floor club, lobbies, and outdoor areas, according to reporting by Dallas News.
Why It Matters for Las Colinas
The sale highlights an ongoing push to reposition suburban office campuses with hospitality-style amenities and more flexible office options, a strategy that designers and contractors at Williams Square say has guided the recent round of improvements. Local developers and project partners cite fresh neighborhood destinations and tenant moves, including the Big 12 Conference headquarters inside the towers, as proof that Las Colinas is competing for headquarters and creative-office users, according to Pacific Builders.
The ownership transfer consolidates control of one of North Texas's most recognizable suburban office addresses and keeps it in the hands of investors already deeply involved with the asset. Market watchers will be tracking leasing trends and tenant shuffling as the partners work to translate recent upgrades into steadier occupancy and rent growth.
