The Ardsley

The listing for this prewar triplex penthouse on the Upper West Side says it's "like a house hovering twenty-two floors above Central Park," but one look at the sprawling floor plan suggests that "mansion" might be a better word. Five bedrooms may sound ordinary, if luxurious, but countless other rooms and suites, three enormous terraces on the middle floor, a wraparound terrace on the bedroom floor and helicopter views in every direction put this iconic home atop a classic Emery Roth-designed co-op at 320 Central Park West in a class by itself—and its $20 million ask certainly reflects its status.
