Stack Infrastructure has completed structural work on the first building at its Stafford Technology Campus in Stafford County, Virginia, marking a significant milestone for what the company has described as the largest project investment in the county's history.

Topping Out at Stafford Technology Campus

Stack announced the topping out of the first building at the Stafford Technology Campus this month, signaling the completion of external construction work on the initial structure.

The achievement comes just over a year into the project, during which construction teams logged more than 425,000 hours of work, moved three million cubic yards of earth, and built 4,000 feet, or 1,219 meters, of retaining walls.

The topping out represents the completion of structural work on the first of what will eventually be 19 data center buildings spread across the campus.

Scale and Scope of the Campus

At full build-out, the Stafford Technology Campus is planned to deliver more than 1 gigawatt of capacity across 19 data centers situated on 500 acres.

Stack has characterized the project as the largest investment in Stafford County's history, underlining the scale of commitment the company is making to the region.

The campus is located on the east side of US Route 1 at Interstate 95 in Stafford County, which lies to the south of Prince William County and southeast of Fauquier County, along the Potomac River.

Recently, STACK Infrastructure announced plans for a $73.5 billion data center campus in Southern Virginia.

Background and Site History

Stack announced the Stafford Technology Campus in January 2025. The site was previously owned by real estate firm Peterson Companies, which first filed to rezone the land for data center use in 2023.

Stafford County is not widely known as a hub for data center development, though in recent years it has lowered taxes on data center equipment, a move that has made it more attractive to operators in the industry.

Stack's Broader Virginia Footprint

The Stafford Technology Campus is part of a wider expansion strategy that Stack is pursuing across Virginia.

The company currently lists 10 campuses in operation and under development across Northern Virginia, representing a total capacity of more than 2.4 gigawatts across approximately 960 acres.

Beyond Stafford County, Stack announced plans last year for a 144-megawatt campus in Loudoun County, Virginia.
