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.Photos from around the city show the skyscraper from different angles and in varying lighting conditions. The top half of the 100-foot-tall architectural spire should be put back in place in the coming months, once all of the curtain wall glass has been installed.

Meanwhile, installation is continuing on the windows that enclose the 1,000-foot-high public observatory, called The Summit. Designed by Snohetta and managed by SL Green, the three-story facility is located around the first setback on the southern elevation. This space can be seen in the below photo adjacent to the Chrysler Building’s crown, indicated by the more transparent glass panels.
