Nearly one-third of the new crop of South Loop rentals coming to market this year are housed in a single building, and Chicagoans are flocking to the southern edge of Grant Park to see what all the buzz is about. NEMA Chicago, the city’s tallest residential tower, encompasses 800 new luxury rentals ranging in size from studios to four bedrooms and featuring floor-to-ceiling windows with panoramic views of the Windy City and Lake Michigan. The Rafael Viñoly-designed skyscraper is also home to a suite of amenities spanning 70,000 square feet that includes everything from a regulation boxing ring and a 75-foot indoor swimming pool to a lounge equipped with arcade cabinets and large televisions perfect for watching a Cubs or Bears game with friends.
