56 Leonard Street (known colloquially as the Jenga Building) is an 821-foot-tall (250 m), 57-story skyscraper on Leonard Street in the neighborhood of Tribeca in Manhattan, New York, United States. The building was designed by the Swiss architecture firm Herzog & de Meuron, which describes the building as "houses stacked in the sky." It is the tallest structure in Tribeca.

The building has 145 condominium residences priced between US$3.5 million and US$50 million. Residences range in size from 1,418 to 6,400 square feet (131.7 to 594.6 m2) and include two to five bedrooms all with private outdoor spaces.

As of May 2013, 70% of the building had sold. According to building developer Izak Senbahar, the building was 92% sold in seven months. In June 2013, a penthouse at 56 Leonard went into contract for US$47 million, making it the most expensive residential property ever sold below Midtown Manhattan. The building was completed in 2017.


Alexico Group's Izak Senbahar purchased the land and the air rights in 2007 from the New York Law School for US$150 million. Construction began that same year. Foundation work on this tower began in 2008, but was shut down before the end of the year when the project was put on hold. After nearly four years, construction finally resumed in October 2012.

In 2013, the developers secured a US$350 million loan from a syndicate led by Bank of America.

Architecture and design

56 Leonard is designed by the 2001 Pritzker Prize winning Swiss architecture firm Herzog & de Meuron. Anish Kapoor, known for the public sculpture Cloud Gate in Chicago, designed a similar sculpture to sit at the base of the building. Herzog & de Meuron also designed the building's interiors, which include custom designed kitchens, fixtures, bathrooms, and fireplaces. Goldstein, Hill & West Architects LLP is the architect of record.

There is 17,000 square feet (1,600 m2) of amenity spaces on the ninth and tenth floors, including a 75 ft (23 m) pool, a 25-seat screening room, a private dining room, and a children's playroom. The building has a total of ten elevators; owners will share a hallway with at most one other apartment. The developers also figured a generator on the ninth floor into the plans.

There are eight full-floor apartments at the top, ranging from 5,200 to 6,400 square feet (480 to 590 m2), with 14-to-19-foot-high (4.3 to 5.8 m) ceilings. In addition, the building features a double-height lobby sheathed in "gleaming" black granite.
