270 Park Avenue’s Demolition is Complete While New Steel Superstructure Rises in Midtown East

Demolition of the Union Carbide Building, JP Morgan Chase‘s former 52-story, 707-foot-tall headquarters at 270 Park Avenue, is now complete as work progresses on its supertall replacement. The remnants of the core and lower levels of the mid-century skyscraper were quickly dismantled and removed since our last update on the Midtown East project just a mere month ago. Meanwhile, on the opposite side of the full-block parcel, steelwork is continuing on the new 2.5 million-square-foot, 1,425-foot-tall tower, which will become one of the tallest structures in New York City. The large rectangular site is bound by Park Avenue to the east, Madison Avenue to the west, East 47th Street to the south, and East 48th Street to the north.

Our photographs from last month showed the temporary steel platform for the construction crane that helped to bring down the old steel structure attached to the final portion of the core and inner framework of deep trusses. All of this no longer exists as crews have successfully disassembled the Union Carbide Building over the past couple of years. Fencing, wooden boards, and sidewalk scaffolding surround the footprint of the former edifice. Right now, the absence of the office tower provides a rare unobstructed perspective of the surrounding glass and steel skyscrapers and gives an impression of just how big JP Morgan Chase’s future headquarters will be.

The most striking visual aspect is the sheer scale of the steel columns, beams, and girders that so far only make up about half of the supertall’s base. The rest of the upside down trapezoidal base will soon be built eastward toward Park Avenue.

The diagram below illustrates the steel around the tall ground floor that fans outward at three moments to connect with vertical columns running up varying heights of the supertall. Also shown are trading floors that make up the lowest and largest floor plates, then the repeated pattern of mechanical space, office floors that gradually taper off with height, and amenity spaces found on each of the setbacks. The crown will house the highest amenity space for occupants.

A completion date for 270 Park Avenue has not been publicly disclosed, but YIMBY suspects that to be several years down the road.

  1. Will we get to see a rendering of 270 Park Ave before it actually gets built?

    • I have been wondering that too. I speculated that it could be this Spring, but it seems that might not be happening. Hmmm…

  2. Rest in peace 270 Park Avenue. I hope your replacement will be as much of an architectural wonder as you were, though I think it’ll probably even exceed you. ?

    Looks like “The One” in Toronto.
    But “The One” is going up, while this one is going down.

  4. Anyone have a demo time lapse?
