Hotels with AI integrations and engineered spaces for athletes are coming to Mansfield after Dallas-based developer House of Tangram secured about 30 acres for a public-private partnership project inside the city’s $2.5 billion Staybolt Street Entertainment District.

The project includes a high-tech hotel concept called Cache Legitimate & Kubo, featuring robotic bartenders, drone delivery and immersive media walls; a convention center with more than 33,000 square feet of programmable space; and Carbon Mansfield, touted to be the world’s first patented sports-centric hotel engineered for athletes and competitive teams.

Officials want the Staybolt Street district to be a hub for sports, tech and hospitality along 360 Tollway with a stadium already under construction. 

“When the city of Mansfield reached out, we listened to what they needed and worked with the staff and council to curate what they asked for: a pioneering mixed-use destination positioning the district as one of the most ambitious sports-anchored, technology-integrated hospitality developments in the United States,” said Shawn Ellis, founder and CEO of House of Tangram, the project developer. 

House of Tangram’s project also includes more than 700 multifamily units, 50,000 square feet of medical office space and over 100,000 square feet of retail and restaurant space. Under the public-private partnership, the city will own the convention center that will be built and operated by Carbon Mansfield.

Ellis said the development is designed to be “a live-operating system for modern life: convention centers reimagined, hotels with AI in their walls, retail that moves like culture — think adaptive storefronts, curated activations and brand-first experiences.”

Officials expect to break ground on this project next summer with a targeted completion in mid-2028.

City officials emphasized how Carbon Mansfield’s AI-native platform will offer personalized recovery environments, real-time biometrics and climate systems that adapt to each guest. The hotel will be engineered to optimize recovery, readiness and results, they said.

“Mansfield has always been known for sports, and bringing a hotel concept that focuses on athletes next to our incoming Mansfield Stadium is a home run,” Mansfield Mayor Michael Evans said. 

Carbon Mansfield and the Mansfield Convention Center will be adjacent to the 7,000-seat multisport stadium that’s under construction. Scheduled to open next year, the stadium will be the permanent home of the North Texas Soccer Club, the MLS Next Pro affiliate of FC Dallas and a subsidiary of Hunt Sports LLC.

Krishna Nimmagadda, partner, chief technology and strategy officer at House of Tangram, said, “We’re building a tech-native hospitality system from the ground up.” 

Nimmagadda, who co-founded and exited two first-generation data and AI companies before investing in North Texas land, said he could not resist taking on this challenge when he saw the cultural shift this development could bring. 

One multifamily community planned is Steam, which will offer 320 lofts with rooftop gardens and communal kitchens. The other, Verona Gardens, will have up to 400 smart, “wellness-first” homes with hydroponics, pet studios, green roofs and built-in climate intelligence, officials said.

Jason Moore, Mansfield Economic Development Corp. executive director, said the development will realize a bold vision for the city, elevating its regional identity and opportunity for tourism.

“We are excited to see this catalytic investment come to life in Mansfield,” he said.

The Beck Group serves as the development manager, fiduciary and one of the general contractors.
