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.

111 West 57th Street contains 60 luxury condominiums: 14 in Steinway Hall and 46 in the tower. The residential tower has a glass facade with piers made of terracotta; its pinnacle contains setbacks on the southern side. The tower is the fourth-tallest building in the United States as of November 2022, as well as the thinnest skyscraper in the world with a width-to-height ratio of about 1:24.

The residential tower atop Steinway Hall is one of the tallest buildings in the United States, as well as the thinnest skyscraper in the world with a width-to-height ratio of about 1:24. Due to its slenderness, the top stories sway several feet during high winds. The building has been characterized as part of a new breed of New York City “pencil towers”. The tower’s northern elevation rises directly up to the pinnacle, and the southern elevation contains several setbacks as the tower rises, thinning the tower’s footprint on higher floors. The pinnacle’s lighting pattern was commissioned by L’Observatoire International. Because of the shape of the tower’s pinnacle, 111 West 57th Street is nicknamed “Stairway to Heaven”.

111 West 57th Street’s interior spaces were designed by Studio Sofield, though the interior of the original Steinway Hall was planned by Walter L. Hopkins. There are 60 apartments in total: 46 in the tower and 14 in Steinway Hall. According to the New York City Department of City Planning, the building has a gross floor area of 303,225 square feet (28,170.5 m2).

The 46 condominiums in the building’s tower range from 3,873 to 7,128 square feet (359.8 to 662.2 m2). The apartments start above the 17th story, numbered as floor 20, because the views of Central Park from the lower floors are obstructed by neighboring buildings. The units are mostly three-bedroom apartments each occupying one full floor, except for seven duplex units on floors 60–61 and 72–83, which each have between two and four bedrooms. Many of the stories are open in plan and have 14-foot (4.3 m) ceilings. As of 2018, prices ranged from $16 million for a studio apartment to over $66 million for the triplex penthouse.
