This series began with audience data, so honesty first: Ashburn appeared in our readership numbers largely because of machines — it is the heart of Data Center Alley, and traffic that exits through its networks wears its name. But follow the geography one layer down and the mirage resolves into a real market. Loudoun County, which Ashburn sits in, is one of the fastest-growing counties in the United States, and Northern Virginia’s dominant health system is in the middle of the largest building program in its history. The data centers and the hospitals turn out to be expressions of the same fact: this is where the growth is, and growth has to be cared for. Here is the demand map.
Two hospitals at once: Inova’s replacement era
Inova Health System — the Washington region’s largest private employer, with roughly 26,000 staff and a budget approaching $7 billion — is building two hospitals simultaneously, both scheduled to open in late 2028. In Alexandria, a 1.1-million-square-foot medical campus is rising on the former Landmark Mall site: a 192-bed hospital, a cancer center, and a specialty care center, inside a mixed-use district of housing and retail called WestEnd. In Fairfax County, the 110-bed Franconia-Springfield Hospital is going up attached to Inova’s existing outpatient HealthPlex. Combined, Inova puts the investment at $2.5 billion. When both open, the current Alexandria hospital — on its Seminary Road site since 1962, in an institution that dates to 1873 — will close, and its land is expected to be redeveloped around housing.
Read the Landmark project as the era’s emblem: a dead suburban mall becoming a hospital campus woven into a residential district. The line between a retail development and a healthcare development has dissolved into a single site plan — the amenity economy and the care economy poured into the same concrete.
Loudoun: the tower that filled up
In Leesburg, Inova Loudoun Hospital recently completed the final phase of a $300 million master plan: a seven-story, 382,000-square-foot patient tower carrying 228 beds and an expanded NICU, built for a county that keeps outrunning its forecasts. The proof that the growth is real sits in the state’s own paperwork. Virginia’s health-planning process records that Inova Loudoun’s inpatient volumes ran at the highest in the region and exceeded its licensed capacity in 2025 — and earlier this year the regional planning agency recommended approving still more beds there, finding the need immediate. A hospital that just finished a nine-figure expansion is already, on paper, too small. For facilities and design teams, that is what proven future demand looks like: not a projection, a regulator’s finding.
Adaptive reuse: the Exxon campus becomes a medical district
The third pattern is conversion. On the 117-acre former Exxon Mobil campus in Merrifield, Inova is renovating four existing office buildings into medical and research uses — including an ambulatory cancer facility and a wet-lab research building side by side — while seeking approval for a first phase of new construction measured in millions of square feet. The campus was famously designed for corporate security, inward and closed; the health system’s project leads describe re-envisioning it to let people in. That sentence is the design brief for a whole category of work in this region: suburban office stock, built for a workforce that no longer fills it, being re-cut into healthcare — with the thirty specialty systems a modern clinical building carries threaded through structures designed for desks.
What the work asks of people
Northern Virginia rewards range. The same market asks one team to phase construction on live suburban campuses, another to convert office buildings into clinical space, another to plan a two-hospital activation in 2028 — and underneath all of it, a facilities workforce for a system adding a thousand employees a year. It is the national renovation economy running at the speed of the region’s growth, in the one metro where the audience data’s ghost town turned out to be a boomtown. Columbus builds against its growth curve; Northern Virginia builds inside its — data centers to the north, subdivisions to the horizon, and hospitals rising to meet both.
