Actor Robert De Niro asked the Landmarks Preservation Commission to let the penthouse at his Greenwich Hotel in Tribeca stand, although it is bigger and stylistically different than what the commission approved. The commission could demand the demolition of the penthouse, but its complete removal seemed unlikely. Critics said the roof appeared too residential and out of context in an industrial neighborhood. Actor and director Edward Burns, whose apartment has a view of the penthouse, called the building “beautiful.” The 88-room hotel opened in April at 377 Greenwich Street and North Moore Street. Nightly rates begin at $525.
