The oldest high-rise development in Midtown, the sub-district was built between 1969 and 1975, with Henri Jova of Jova/Daniels/Busby serving as principal architect.
The three skyscrapers are connected by Colony Square Mall, located beneath a sky-lit atrium and offering a food court, ice skating rink, retail, and an athletic club.
The original architectural and social concept of Colony Square was the USA's first 'micropolis' - the complex designed for urban professionals to live and work in a common space.
Colony Square also contains street-level restaurants, including 5Church Atlanta, Establishment, Chick-fil-A, Starbucks, and Sukoshi.
The deal will include the retail and office space, but not the condominiums and hotel that are part of the complex.
