Plans for 343 Madison Avenue in Midtown East unveil the substantial size and scope of the supertall to take the place of the former Metropolitan Transportation Authority (MTA) headquarters. Boston Properties is developing the project that would comprise 925,630 square feet and rise 1,050 feet tall, with Class A office space above ground-floor retail. The building would yield 5,357 square feet of retail space on the ground floor, 832,613 square feet of commercial office space above, and 84,593 square feet of dedicated mechanical space. The tower would sit on a podium 301 feet tall.
Midtown East Rezoning
Full demolition permits have been filed for 417 Park Avenue in Midtown, Manhattan. According to the filing, the site is owned by GDS Development under the Clover Park Development LLC. It currently houses a 12-story residential building with 28 units. The 143-foot-tall structure was built in 1916 and has a basement, cellar, and penthouse.
Demolition has begun for JP Morgan Chase‘s 52-story former headquarters at 270 Park Avenue, which was once known as the Union Carbide Building. The financial titan is razing the 707-foot-tall mid-century skyscraper to make way for a massive 1,425-foot-tall, 2.5-million-square-foot supertall that will be among the tallest structures in New York City.
The triplet of flat rectangular fins atop the roof parapet of 425 Park Avenue are fully enclosed, while some of the last remaining office floors for the upper tiered section of the 47-story, 897-foot-tall Midtown East skyscraper, are close to being clad. The commercial office project is designed by Norman Foster, head of Foster + Partners, and is being developed by L&L Holding Company LLC. Adamson Associates is the architect of record.
Glass paneling is steadily enclosing the tiered crown of Kohn Pedersen Fox’s One Vanderbilt as the supertall inches closer to completion. Developed by SL Green, the 77-story, 1,401-foot-tall commercial office tower is by far the largest construction project underway in Midtown East and is among the most prominent new additions to the New York skyline.
