One Vanderbilt, a forthcoming supertall designed by our friends at Kohn Pedersen Fox, is expected to top out, at 1,401′, in fewer than two years; in the meantime, new construction photos show its distinctive terra cotta facade. Upon completion, expected to occur in mid-2020—construction is as yet well ahead of schedule—the 77-storey tower will become the New York’s fourth-tallest; it is is expected to reach 50-storeys by the end of 2018, and 37% of its units are already leased. Additionally, the building will feature the city’s fourth-tallest observation deck, at the observatory at One Vanderbilt, which will feature 3-storeys of indoor and outdoor space, and will exist 1,K+’ in elevation. A big draw for prospective leasees are the units’ extremely high ceilings, which range from 14.5′ to 24′, and columnless floorplates. To make this project possible, its developer SL Green spent $220M on a connection to and general improvements of the Grand Central Terminal subway station, adding a 4,K SqFt transit hall for commuters to gather. KPF will also add a 15,K SqFt public plaza along Vanderbilt Avenue to flank the building’s entrance.
