The world's skinniest skyscraper has been completed, adding a new landmark to Manhattan's famous skyline.

Steinway Tower, or 111 West 57th Street, has a height-to-width ratio of 24:1, making it "the most slender skyscraper in the world," according to the developers.

At 1,428 feet, it is also one of the tallest buildings in the Western hemisphere, falling short of two others in New York City: One World Trade Center at 1,776 feet and Central Park Tower at 1,550 feet.

The midtown Manhattan development includes 60 apartments spanning the tower's 84 stories and the adjacent Steinway Hall building.

The tower was designed by New York architecture firm SHoP Architects and built by JDS Development, Property Markets Group and Spruce Capital Partners, which began construction in 2013. Gregg Pasquarelli, principal at SHoP Architects, called the building "a project of extraordinary proportions and epic grandeur" in an email to CNN.

111 West 57th Street, also known as Steinway Tower, is a supertall residential skyscraper in the Midtown Manhattan neighborhood of New York City. Developed by JDS Development Group and Property Markets Group, it is situated along Billionaires' Row on the north side of 57th Street near Sixth Avenue. The main portion of the building is an 84-story, 1,428-foot (435-meter) tower designed by SHoP Architects and completed in 2021. Preserved at the base is the 16-story Steinway Building (also Steinway Hall), a former Steinway & Sons store designed by Warren and Wetmore and completed in 1925, which originally carried the address 111 West 57th Street.
