American Copper Buildings – and formerly known as 626 First Avenue – the 41- and 48-storey residential towers on First Avenue and 36th Street overlooks the East River.
The upper half of the skyscrapers bend slightly outward, drawing references by the local media to the Leaning Tower of Pisa. The firm has described them as "dancing" towers.
At floors 27 to 29 – the point where the buildings nearly touch – the towers are linked by a skybridge suspended 300 feet above the ground. It is the first major new skybridge to be built in New York in nearly 80 years.
