Hovering above Manhattan’s skyline, the most exclusive penthouse in America’s skinniest skyscraper is now on the market—for a cool $110 million.

A Vertical Mansion in the Sky

The Steinway Tower penthouse spans floors 80 through 83 of the iconic tower, soaring above Billionaires’ Row. At 11,480 square feet, the quadplex isn’t just massive—it’s masterfully designed. With five bedrooms, six bathrooms, and over 600 square feet of private terrace space, the home blends ultimate privacy with jaw-dropping panoramas of Central Park and beyond.

Studio Sofield crafted the interior with meticulous attention to detail. The first floor boasts a grand Entertaining Suite ideal for upscale gatherings. On the third level, a sprawling Primary Suite offers retreat-like seclusion. Capping it all off, the top-floor Crown Suite includes a private bar and an in-home screening room for cinematic nights above the city.

Old-World Elegance Meets Modern Marvel

While the tower was completed in 2022, it retains a connection to New York’s history—it stands on the former site of Steinway & Sons piano company, and still houses the original 1925 Steinway Hall. Designed by SHoP Architects and developed by JDS Development Group alongside Property Markets Group and Spruce Capital Partners, the building elegantly merges heritage with high-tech luxury.

The penthouse features soaring 14-foot ceilings and floor-to-ceiling windows that flood every level with natural light. White macauba stone flooring lines the entry, while custom 9-foot doors—outfitted with bronze handles and hinges—add a touch of tailored craftsmanship. There’s direct elevator access, a custom staircase, and even a private internal elevator for seamless movement between floors.

A Private Observatory Above the City

Beyond the usual luxury offerings, this sky palace includes zoned climate control, outdoor terraces, and a one-of-a-kind observatory for taking in New York’s ever-changing skyline. Outside, the tower’s terracotta façade shifts in color and texture depending on light and angle, creating an ever-evolving visual experience that’s uniquely mesmerizing.

And yes, even the swimming pool breaks convention. “I didn’t want it to feel like a normal swimming pool,” said Studio Sofield founder William Sofield in an interview. “It has wood paneling, gold-leaf detailing, vaulted ceilings, and draperies—it’s not something you’d find anywhere else.”

If you’re in the market for a home that defies gravity and expectation, the Steinway Tower penthouse just might hit the high note.
