15 Penn Plaza, also known as the Vornado Tower, was a proposed 68-story tower in the Midtown Manhattan district of New York City planned by Vornado Realty Trust. It would have had 430 units and 2,050,000 square feet (190,451 m²) of floor space. The Hiller Group is the designer. Despite only having 68 floors, it would be just 34 feet (10 m) shorter than the 81-year-old Empire State Building, which has 102 floors.
The Empire State Building's owner, Anthony Malkin, asked the City Council on August 24, 2010, to deny permission for the construction of the Vornado Tower. Malkin's reasoning is that the new building would alter the skyline and obscure the view of the western side of the Empire State Building. Located at Seventh Avenue between 32nd and 33rd Streets on the site of present-day Hotel Pennsylvania, opposite Pennsylvania Station - a major transit hub for the Long Island Rail Road, New Jersey Transit, Amtrak and the New York City Subway - the proposed building would add a concourse improving access within Penn Station and adding several new subway entrances.
In exchange for increases in height and density for the building, Vornado would undertake $100 million in transit-related improvements that would reopen the "Gimbels passageway", which was blocked off in 1986 and would reconnect Penn Station to Herald Square at Sixth Avenue and the 34th Street - Herald Square station (B D F M N Q R trains) and the 33rd Street terminal of the Port Authority Trans-Hudson (PATH) train, which provides access to Hoboken and Journal Square trains. An updated passageway would be built to the standards of "the elegant and efficient passageways at Grand Central and Rockefeller Center" and would also have integrated access to the proposed New Jersey Transit terminal that would be constructed as part of the Access to the Region's Core tunnel that was to be constructed under the Hudson River.
