Supertall

New renderings have been revealed for 350 Park Avenue, a proposed supertall office skyscraper in Midtown East, Manhattan. Designed by Norman Foster of Foster + Partners and developed by Ken Griffin, Vornado Realty Trust and Rudin, the 62-story structure is planned to rise roughly 1,600 feet tall and yield 1.8 million square feet of office space, with 54 percent to be occupied by the hedge fund Citadel LLC. The project site is bound by East 52nd Street to the north, East 51st Street to the south, and Park Avenue to the east.

Exterior work is continuing on JPMorgan Chase‘s 1,388-foot supertall headquarters at 270 Park Avenue in Midtown East. Designed by Lord Norman Foster of Foster + Partners with Adamson Associates as the architect of record and developed by Tishman Speyer, the topped-out 60-story skyscraper will yield 2.5 million square feet of office space with a capacity of 15,000 employees, and will become the tallest structure in New York completely powered by hydroelectric energy. AECOM Tishman is the general contractor for the project, which occupies a full city block bound by East 48th Street to the north, East 47th Street to the south, Park Avenue to the east, and Madison Avenue to the west.
