AT&T’s planned Plano headquarters build targeted to start Dec. 1, state filings indicate

AT&T is preparing for a significant construction project in Plano, Texas, with the early stages reportedly scheduled to begin on Dec. 1, according to state filing information cited in a Yahoo Finance report.

The report says the development, described as a Plano headquarters campus, has a price tag of more than $1 billion. It also indicates the project’s construction kickoff is set for Dec. 1, with completion targeted for March 31, 2029.

The filing information referenced in the report names KDC as the construction party involved in the project. KDC is listed in connection with beginning work on the campus, suggesting AT&T’s plan is in the execution phase rather than still at an early planning stage.

While the report provides timing and cost framing, it does not spell out which specific facilities or building components are included in the campus, nor does it describe whether the effort is primarily new construction, a renovation effort, or a mix of both.

AT&T’s decision to pursue a large campus in the Dallas-Fort Worth region reflects a broader pattern in telecom and technology-heavy corporate real estate, where companies consolidate operations into purpose-built sites to support long-term workforce planning, engineering functions, and vendor collaboration. For carriers like AT&T, headquarter and major campus investments also tend to align with internal priorities across network planning, customer technology, and corporate operations.

In a separate sense, the project’s timeline highlights the long lead times involved in large-scale commercial construction, particularly when schedules must account for permitting, site work, procurement, and building fit-outs that can extend across multiple calendar years.

The Yahoo Finance item does not indicate whether AT&T or the involved parties will provide additional milestones before the Dec. 1 start date. It also does not detail whether the campus will be occupied in phases or whether the March 31, 2029 date refers to substantial completion, final turnover, or another contractual milestone.

For investors and observers, the next indicates to watch are any official AT&T updates around the project, including budget refinements, progress markers, or changes to the timeline, as well as any follow-on disclosures that could clarify the scope of work and expected operational impacts.
