First Building at Stack’s 1GW Data Center Campus in Virginia Tops out in Stafford County

Stack Infrastructure has completed external construction work on the first building at its new campus in Stafford County. The company announced the topping out of the first building at the Stafford Technology Campus (STC). In just over a year, project teams have recorded more than 425,000 hours of work, moved around three million cubic yards of earth, and constructed 4,000 feet (1,219 meters) of retaining walls.

Stack Infrastructure’s Stafford Technology Campus (STC) is located in Stafford County, which lies south of Prince William County and southeast of Fauquier County along the Potomac River. The county is not traditionally known for major data center development, although it has recently reduced taxes on data center equipment to attract investment. At full build-out, STC is expected to deliver more than 1GW of capacity across 19 data centers on a 500-acre site, which the company describes as the largest investment project in Stafford County’s history.

Announced in January 2025, the Stafford Technology Campus site was previously owned by real estate firm Peterson Companies, which filed to rezone the land on the east side of US Route 1 at I-95 for data center use in 2023. Stack Infrastructure currently operates and develops 10 campuses across Northern Virginia, totaling more than 2.4GW of capacity across roughly 960 acres.
