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.

According to reports, the proposed interior layout includes an “entertaining suite” on the first level and a luxurious “primary suite” on the third, while the top floor houses a “crown suite” complete with a bar and a private screening room.

Designed by Studio Sofield, the penthouse features five bedrooms, six bathrooms, and two private terraces. The interior design is marked by a blend of classic opulence and modern grandeur, using materials such as marble, blackened steel, limestone, and velvet.

Common spaces in the building are adorned with artworks by Pablo Picasso and Henri Matisse, contributing to the building’s atmosphere of refined luxury.

Steinway Tower, completed in 2022, was developed by JDS Development Group and Property Markets Group and designed by SHoP Architects in collaboration with interior designer William Sofield. Erected on the former site of the historic Steinway & Sons piano showroom, the building merges new construction with the preserved 1925 Steinway Hall at its base — a nod to the city’s architectural and cultural history.

With a height-to-width ratio of 24:1, the tower holds the title of the most slender skyscraper in the world, a feat of engineering made possible by modern advancements in building materials and design. This structural slenderness also places it among the tallest residential buildings in the Western Hemisphere.

The façade, composed of terracotta and bronze, reflects light in a way that changes its appearance throughout the day — a dynamic visual feature intended by its architects to echo the stylistic richness of New York's Gilded Age.

"We’ve all been to very luxurious places, but I wanted to create a building that could not be anywhere else in the world,” said William Sofield in an interview with CNN in 2022. “I know so many people might have multiple homes, who will have apartments here. And I wanted to create a very distinct experience that could only be had in New York.”

Residents of Steinway Tower enjoy an array of luxury amenities, including an 82-foot swimming pool, state-of-the-art fitness center, private dining spaces, and a landscaped outdoor terrace. Concierge services and private elevator access add to the level of exclusivity.

The tower is located on Manhattan’s so-called Billionaires’ Row, a stretch of ultra-luxury high-rises bordering Central Park South that has become synonymous with elite real estate.

Nearby buildings include Central Park Tower — currently the second-tallest building in New York City after One World Trade Center — and 220 Central Park South, where hedge fund billionaire Ken Griffin famously purchased a penthouse in 2019 for $238 million (£184.7 million), the highest price ever paid for a home in the United States.

Though ultra-luxury sales have seen fluctuations due to shifting market conditions and changing global economic trends, properties like the Steinway Tower penthouse are still sought after.
