1. Central Park Tower

Central Park Tower-Adrian Smith + Gordon Gill Architecture -SOM-57th Street-NYC
The Central Park Tower has gone by many names: The Nordstrom Tower, 216 West 57th Street. When completed in 2019, it is expected to reach 1,539 feet and 99 stories, with a Nordstrom department store and hotel on the lower levels. It will also have a controversial cantilever over the Arts Students League, a landmarked building next door. Extell has deliberately kept information on the design hard to come by, so time will only tell its final form and height.
