The team behind some of Dallas-Fort Worth’s biggest corporate campuses is looking to build one of the largest office hubs the region has ever seen. If all goes according to plan, Frisco could become a top contender for the next region-defining business relocation.
Developer Fehmi Karahan and KDC plan to develop 11 million square feet of custom office space within the $10 billion, 2,545-acre Fields development in Frisco, the group told The Dallas Morning News. Companies looking to relocate to the site would be offered everything from midrise campuses to trophy towers.
The site could bring the next Fortune 50 company to the region, embedding it within a megadevelopment that includes multimillion-dollar homes, the Universal Kids resort and the PGA of America headquarters, Omni PGA Frisco Resort & Spa and more.

The end result could be one of the largest office developments in D-FW, rivaling the 15 million-square-foot Legacy Business Park and its offshoots, the partners said. The 11 million square feet of office space in the Fields would be equal to more than 17 football fields.
“There aren’t many 100-acre or 200-acre parcels left in Legacy and other [sites]. We can do a 200-acre campus [at Fields] if there’s a larger user,” Karahan said. “The new company coming — the next Boeing, the next Caterpillar — is going to … look at the talent, look at the education and look at the housing and say this is where most of the people we want to hire live.”
Karahan and KDC already have the track record to back up the vision. The partnership was behind major corporate moves to Legacy West — Toyota’s North American headquarters and major hubs for JPMorgan Chase, Liberty Mutual and FedEx.
KDC has established itself as one of the region’s premier headquarters specialists. The group is developing AT&T’s billion-dollar headquarters at 5400 Legacy Drive in Plano. Demolition of the former EDS campus began earlier this year, and construction of the new buildings is expected to start soon.

“This is getting the band back together,” said KDC president Eric Hage. “We think Fields is the next frontier.”

The partners will have plenty of room to work with in Frisco.
They’ll have nearly 700 acres to offer, larger than their previous projects. The area is zoned for any office use and much of it is along the Dallas North Tollway frontage road. KDC will market the land to companies looking to expand or relocate in the Dallas area.
KDC is in the early stages of marketing the property to companies. Hage estimates that office construction could start at Fields sometime in 2027. Neither party disclosed which companies might be eyeing the Frisco site for a new project. However, Hage said the site could host a range of users.
“We are going to see companies that are looking for sizes that are significant, 1 million square feet plus,” he said. “We’re also going to see companies looking for 100,000 square feet. … The beauty of Fields is the flexibility.”
Another appeal are the amenities and ongoing development that would welcome companies and their employees, the group said.

Fields West, a pedestrian-friendly, mixed-use project within the larger development, has 44 leases signed with retailers and restaurants. The segment will include 360,000 square feet of shopping, dining and entertainment. The recent agreements bring the site to 75% preleased.
Roughly 350,000 square feet of office and The Wentwood, a 1,150-unit apartment project, sit above the retail. The apartments, developed by Columbus Realty Partners, have begun preleasing. The first residents are expected to move in early next year.
The office demand is already bubbling. One large company that looked at the site but ultimately passed was AT&T, Karahan previously told The News. The developer said he got the sense that the site was just too far north for the telecom giant. He pitched Fields in an initial meeting with AT&T representatives.
Current plans for Fields call for up to 14,000 homes and apartments, up to 11 million square feet of office space, and roughly 1 million square feet of retail, restaurant and entertainment space. The total value of the project ranges from $10 billion to $15 billion, Karahan said.
Fields is the result of a partnership between Karahan and Hunt Realty, as well as investors Chief Partners and Crosstie Capital. The partners teamed up in 2018 to acquire what was the largest remaining vacant property in Frisco — a tract that belonged to the estate of Dallas businessman Bert Fields.

The planned office development comes as Collin County continues its explosive population growth and D-FW’s office market continues its post-pandemic rebound.
Collin County added nearly 43,000 residents between 2024 and 2025 — the second most in the United States, behind only Houston’s Harris County, U.S. census estimates show.
Real estate firm JLL tracked 2.3 million square feet of office leases signed in the third quarter of this year. Recent groundbreakings at 8300 Douglas and 2626 McKinney have kept Dallas among the most active markets for office construction, trailing only New York.
“We think we have the most premier location,” Karahan said.
