Construction has begun on the structural frames for 425 Park Avenue‘s trio of decorative parapet fins in Midtown East. The 47-story, 897-foot-tall building 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.
New photos from street level and from above document the installation process. A temporary brace between all three is currently in place.
The fins, which will be constructed of glass and will be illuminated at night, could easily be finished before the end of the summer. Meanwhile, the curtain wall continues to ascend the main Park Avenue elevation. The backside of the skyscraper makes extensive use of opaque gray-colored paneling interspersed by tall strips of floor-to-ceiling glass. Most of the shear concrete walls that make up this side of the structure house the elevator cores, egress staircase, and mechanical shafts.
425 Park Avenue should be finished by the end of 2020.
