Overview of Plaza 400 at 400 East 56th Street

Plaza 400 is a 40-story, 591-unit cooperative located at 400 East 56th Street in the Beekman/Sutton Place enclave. Originally built in 1968 as one of the tallest towers in the area, it was designed by Philip Birnbaum and Associates for Bertram F. Bonner and converted to a cooperative in 1981. Known for its distinctive "Maltese Cross" shape, this white-brick building features angled balconies, lush landscaping, and occupies less than 40% of its large site, creating a sense of openness uncommon in the neighborhood.

The impressive two-story lobby, designed by Raymond Loewy and William Snaith Inc., showcases a chandelier reportedly ordered by the Nizam of Hyderabad in the 1840s. Outside, a circular driveway, polished red-granite base, and central fountain enhance the building's grand entrance.

Plaza 400 offers an array of amenities, including a rooftop SkyTop Lounge with a heated seasonal pool and 360-degree views, a state-of-the-art fitness center, a children’s playroom, bike room, laundry facilities, and personal storage bins. Additional services include 24-hour doorman and concierge service, on-site management, a resident superintendent, valet parking, and a shareholder discount at the attended garage, which features Tesla charging stations. Utilities, including central air and heat, are included in the maintenance fees.

The building permits co-purchases, guarantors, pied-Ă -terre usage, and subletting with board approval. However, washer/dryers and pets are not allowed. There is a 2% flip tax payable by the buyer.

Situated near Sutton Place's charming parks, gardens, and restaurants, Plaza 400 provides easy access to Central Park, theaters, museums, and the East River Greenway. It combines a peaceful residential setting with proximity to the vibrant energy of Midtown Manhattan.

Broker & Buyer Comments

This "impeccably maintained" 40-story white-glove cooperative offers "old-world elegance" starting with its "grand entrance" featuring a "stunning 1840s Indian Palace chandelier." The "resort-like" amenities include a "coveted" rooftop pool, well-equipped gym and exclusive Skytop Club, while "meticulous" service comes via doorman, concierge and dedicated staff. Set in the "prestigious" Sutton Place neighborhood, it provides "seamless access" to upscale shopping, dining and transportation. While the co-op board maintains "stringent standards," residents praise the building's "financial stability" and "pristine upkeep." The "prime location" offers easy access to Bloomingdale's, fashionable boutiques and FDR Drive.

Sales History

Price/Room (Est)

Why are we displaying the estimated price per room?

For some co-ops, instead of price per square foot, we use an estimate of the number of rooms for each sold apartment to chart price changes over time. This is because many co-op listings do not include square footage information, and this makes it challenging to calculate accurate square-foot averages.

By displaying the price per estimated room count, we are able to provide a more reliable and consistent metric for comparing sales in the building. While we hope that this gives you a clearer sense of price trends in the building, all data should be independently verified. All data provided are only estimates and should not be used to make any purchase or sale decision.
