New York City is no stranger to architectural marvels, but one of its latest creations redefines what’s possible in urban design. Rising high at 111 West 57th Street, this slender skyscraper isn’t just impressive — it holds the title of the narrowest tower in the world.
A Record-Breaking Feat of Engineering
Designed by SHoP Architects alongside Studio Sofield, this ultra-slim structure is a stunning marriage of historic elegance and cutting-edge engineering. Known collectively as Steinway Hall and Steinway Tower, the project combines a restored historic building with a soaring new addition that reaches an incredible height of 435 meters — all on a footprint that’s barely 17 meters wide. With a jaw-dropping slenderness ratio of 24:1, it’s a skyscraper that pushes the very limits of architectural daring.
Inside: Where Luxury Reaches New Heights

Step beyond the sleek exterior, and the real magic unfolds. The Steinway Tower is home to luxurious private residences, each offering breathtaking panoramic views over Manhattan and Central Park. But it’s not just about the vistas — every detail inside has been carefully curated to reflect timeless elegance.

The interiors are spacious and refined, featuring expansive living rooms, formal dining areas, and wide-plank oak floors. Throughout the residences, the designers paid homage to the historic Steinway Hall by weaving original architectural elements into the modern decor, creating a sense of continuity between past and present.

From the dramatic entrance lobby to the exclusive indoor swimming pool, the building offers the kind of amenities that define luxury living in New York’s competitive real estate market.

A Symbol of Ambition and Beauty
Beyond its technical achievements, the Steinway Tower has quickly become a symbol of ambition, artistry, and the sheer will to challenge conventional ideas of what skyscrapers can be. At once a nod to the city’s rich architectural past and a bold step into its future, this slender giant offers a living experience that’s truly one-of-a-kind.
