A sprawling penthouse atop Manhattan’s Steinway Tower — considered the world’s skinniest skyscraper — has been listed for $110 million (£85.3 million), marking one of the most exclusive and architecturally unique properties currently on the market in New York City.

Occupying the top four floors of the 1,428-foot-tall tower at 111 West 57th Street, the residence — referred to as a "quadplex" — extends from floors 80 to 83. The unit offers sweeping, 360-degree views of Manhattan, including a dramatic vista over Central Park.
