AT&T has broken ground on its global headquarters campus at 5400 Legacy Drive in Plano, with KDC as developer. The ceremony was held November 12, with the first fiber connection installed at the site. The Gensler-designed campus spans 2.2 million square feet across seven buildings of six to eight stories.

The project includes three parking garages, a welcome center and a 280-foot communications tower topped with AT&T's globe logo. Amenities: a soccer field, lake, food hall, daycare, pedestrian bridges, hike and bike trails, and a public plaza. The site formerly housed the Electronic Data Systems headquarters, imploded in August.

The campus will accommodate roughly 10,000 employees, with partial occupancy targeted for the second half of 2028 and full completion by March 2029. KDC is seeking about $3.5 billion in credit tenant lease financing arranged by CGA Capital and CBRE.

Plano approved up to $20 million in incentives plus a 65 percent property tax rebate for 25 years. Construction formally begins December 1.
