New public filings offer an early peek at some of AT&T’s plans for its multibillion-dollar headquarters in Plano.
A recently filed rezoning request shows that the telecom giant seeks to build what appears to be a mid-rise office building. A large, needle-like sculpture with the AT&T logo and a communications antenna would tower over the structures. Documents refer to the project as SEC Parkwood at Legacy.
Details shown in the filing are preliminary and likely to undergo substantial changes. AT&T declined to comment on the filing.

The move has stirred both controversy and soul-searching among Dallas officials, as well as sparking conversations about the future of the city’s urban core.

Property owners, Dallas-based investment firm NexPoint, are seeking to rezone 1.4 acres at the southeast corner of Legacy Drive and Parkwood Boulevard in Plano. Representatives for the firm could not be reached before publication.
Initial documents show developer KDC, architecture firm Gensler and landscape architects SWA are involved in the efforts. KDC and SWA did not respond to calls and emails seeking comment.
“We are under a strict NDA and must respect the confidentiality of the project. As such, we are unable to answer any questions at this time,” Gensler told The News Tuesday.
A hearing for the zoning case has not been scheduled. The 1.4-acre parcel is a fraction of what AT&T plans to build at the site.
The company announced earlier this year that it planned to move its global headquarters out of downtown Dallas, in favor of a custom-built campus on 54 acres at 5400 Legacy Drive.

Plano city officials approved a $20 million incentive package and a lengthy tax rebate for the Fortune 500 firm last month. It’s the largest incentive package the city has given to a private employer.
Under the terms of the Chapter 380 agreement, AT&T must spend a minimum of $1.35 billion in construction costs on the project.
The telecom giant must also build a minimum of 2 million square feet of office, amenity and retail space at the site, eventually employ 10,000 full-time workers at the property and occupy the planned headquarters for 25 years.
In addition to the $20 million in grants, the firm will also receive a 65% property tax rebate on improvements made at the site over 25 years, starting in 2030. The rebate could be extended for an additional decade at 25%, if AT&T purchases the site.
Stankey said the firm is targeting partial occupancy for the new headquarters “as early as the second half of 2028.”
AT&T’s lease at the 37-story Whitacre Tower at 208 South Akard St. runs through Dec. 31, 2031.
