3. 111 West 57th Street (1,428 feet)

Perhaps of all the supertall skyscrapers going up on 57th Street, this one above Steinway & Sons may have captured the imagination of New Yorkers because it’s simply so skinny. With a width-to-height ratio of 1:24, it has been claimed that this SHoP Architects designed building will be the world’s thinnest skyscraper at just 60 feet narrow.
Part of the plan was also to make the Steinway & Sons flagship showroom (since vacated by the piano company) an interior landmark which will include a single-layer glass wall to make the interior visually accessible to passers-by.
