The Skinniest Building in the World Measures 435 Meters in Height. Called Steinway Tower, the Skinniest Building in the World Is Located in the United States.
Located next to the famous Central Park in New York, the building at 111 West 57th Street, known as Steinway Tower, is a residential skyscraper notable for being the skinniest building in the world. Situated in the heart of Midtown Manhattan, this impressive building redefines urban architecture with its slender and elegant structure, attracting the attention of everyone passing through this iconic region.
Skinniest Building in the World Measures 435 Meters in Height
Developed by JDS Development Group and Property Markets Group, the main part of the skinniest building in the world is a 84-story tower measuring 435 meters developed by SHoP Architects, and was completed in 2022, announced as ready for residents to move in.
The skinniest building in the world was constructed at the base of the existing 16-story Steinway Building, an old store designed by Warren and Wetmore and completed in 1925, which originally carried the address 111 West 57th Street.

The tower is one of the tallest buildings in the United States, as well as the skinny skyscraper in the world, with a height-to-width ratio of about 1:24, its height of 435 meters sharply contrasting with its “thinness” of 17.5 meters wide.
Despite the size of the new Steinway Tower, it was technically built as an addition to Steinway Hall. Construction of the tower began in 2014, and the building was restored as part of the residential project.
A major initial construction challenge was the foundation of the skinniest building in the world. Engineers had to work around the foundation of the existing old building, in addition to the limited area to accommodate the new structure.
The Foundation of the Skinniest Building in the World Consists of a 4-Meter Concrete Slab
In general, the foundation of the skinniest building Steinway Tower consists of a concrete slab and bases with thicknesses ranging from 1.5 to 4 meters, founded on medium to hard rock of 60 tons per square foot.
The new foundation was adjusted around the foundation of the old building, in order to reduce intervention in the existing structure. The skinniest building in the world is made with reinforced concrete with a 38-meter steel crown.
The gravity system consists of flat concrete slabs cast in place supported by reinforced concrete columns and shear walls.
There are a total of 10 mechanical floors in the tower, and to accommodate the limited space, setbacks and transfers resulting on the south side of the building, several columns that would normally have been located on the south of the building were replaced by a deep concrete beam, leaving two columns on the north side throughout the building.
The typical thickness of the residential slab is 30.5 centimeters, supported by shear walls and only two columns, allowing for a column-free layout in the interiors.
Interior of Steinway Tower
The tower accommodates one residence per floor, plus 14 in the adjacent Steinway building, bringing the total to 60 apartments. The 46 luxury apartments in the new tower of the building range from 359.8 to 662.2 m².
The building tapers to a flat edge at its peak and has its east and west facades clad in terracotta tiles with bronze detailing, while the glass curtain walls face Central Park to the north and Lower Manhattan to the south.
Also in the skinniest building in the world, there is a 25-meter pool, along with other luxury amenities, including a private dining room and a double-height gym with a terrace.
