Located immediately north of Heatherwick Studio’s artificial island park, the Hudson River Park Trust’s newest patch of open public space encompasses 80,000 square feet of rooftop space atop Chelsea’s historic Pier 57. At just shy of 2 acres, the park–dubbed the Pier 57 “Sky Park”–is the largest stretch of public rooftop parkland in New York City. Pier 57 was transformed into a dynamic mixed-use destination that includes office space for Google and a new public park.
