The Steinway Tower.
It's the thinnest skyscraper in the world – and as if that weren't remarkable enough, its interior is also extremely luxurious. At 435 meters tall and with a base width of just 17.91 meters, it holds the record for the world's narrowest skyscraper with a ratio of 1:24. The building stands directly on Central Park in New York, on the site of the former headquarters of the renowned piano manufacturer Steinway & Sons.
Ninety-one stories rise into the sky at 111 West 57th Street, defining the New York City skyline. The building contains a total of 46 residential units – some spanning a single floor, others duplexes. The foyers are finished with limestone, marble, blackened steel, and velvet. The floors are made of solid oak in a smoky gray tone. Original works by Picasso and Matisse are also part of the decor.
