2. 111 West 57th Street
The most slender of them all, 111 West 57th Street has a ratio of 1:23 and will reach 1,438 feet and 80 stories. It has a projected completion date of 2018 and is set back from the street due to its proximity to the landmarked Steinway & Sons building (though the piano maker sold the building in 2013). 111 West 57th Street is designed by SHoP Architects, with a facade of glass, terra cotta and bronze.
