The campus off Sycolin Road was committed before a slab was poured: in November 2023 TA Digital Group signed a single 430 MW build-to-suit lease covering all five planned buildings, 1.92 million sq ft on 145 acres, to one cloud provider it has never named. Its scale bought something rarer than capacity — two independent substations, which the developer describes as increasingly hard to achieve in a core market. Construction began late in 2023, helped by a Leesburg council decision that August allowing 65-foot data centre heights, and the developer funded a new water pump station serving both the site and the surrounding community. Loudoun County issued the tenant fit-out permit for 20335 Celtic Park Drive on 5 February 2025 at a construction cost of $10.7 million. The first two buildings, 745,000 sq ft and 165 MW of IT load, were sold in February 2026.
