Exterior work is progressing on 425 Park Avenue, an 897-foot-tall commercial skyscraper in Midtown East and number 12 on YIMBY’s construction countdown. Designed by Norman Foster of Foster + Partners and developed by L&L Holding Company LLC with Adamson Associates, the 47-story tower will yield 666,966 square feet of office space.
The curtain wall has continued to shape up since our last update back in early September. Since then, the yellow construction crane has been fully disassembled and removed, leaving behind a sliver of floor plates on the first tier to be completed and enclosed. Work is continuing on the steel diamond-shaped frames and triangular glass panels at the first setback, where one of the building’s amenity spaces will be located. Above, a number of scattered window openings are in the process of being installed. Finally, at the roof level, light strips have been installed on the slender western sides of the tower’s signature fins, and what appears to be large LED panels are in place on the northern and southern faces of the outer fins.
YIMBY recently had the opportunity to tour the roof level to get a feel for the views that the building’s uppermost floors will offer. Tenants will have panoramic vistas of Billionaires’ Row, Central Park, the Empire State Building, the Citigroup Center, Jean Nouvel’s 53 West 53rd Street, the East River, Long Island City’s skyline, and even a unique head-on shot of the Chippendale atop Philip Johnson’s 550 Madison Avenue that’s a short walk to the west.
Below are photographs that offer a closer look at the diagonal steel frames on the first setback and around the interior space when the last assembly was about to go up.
425 Park Avenue is expected to be completed sometime in 2021.
