Construction begins shortly on the complete overhaul of the Hampton Mall, into a mixed-use project that will include a new county office building. Mid-September was the anticipated start date for Hampton Park, where Velocity Companies and ArcTrust will bring new retail, apartments, a hotel and office space to about 25 acres just inside the Beltway at Central Avenue, in Capitol Heights. The county will house its Health and Human Services department in a new building, on-site. The church that has made the mall its home for years, the Sanctuary at Kingdom Square, will relocate to Route 301 in Upper Marlboro.
