Sports architecture firm Populous is moving to the Board of Trade building near the Plaza

The firm plans to lease 65,000 square feet in the building at 4800 Main St. The building was bought in January by Mariner Real Estate Management LLC of Leawood. It lost its main tenant last summer when the Chicago Mercantile Exchange halted operations there, ending more than a century of grain trading in Kansas City.
