About This Home

400 E 56th Street #23F

Welcome to Apartment 23F at Plaza 400, a spacious one-bedroom, one-and-a-half-bath residence offering the highly sought-after F-line layout. This home presents a wonderful opportunity to create a space that reflects your own personal style.

A welcoming foyer opens into an expansive living and dining area, highlighted by oversized windows that frame open city views, beautiful skies, and fill the home with natural light from its northern and western exposures. The generously proportioned king-sized bedroom offers excellent closet space and an en-suite full bath with a stall shower. Off the foyer, you'll find additional walk-in closet space, a well-proportioned kitchen, and a convenient powder room for guests.

With its spacious layout, abundant storage, open city views, and endless possibilities, Apartment 23F is ready to be transformed into a beautiful custom home in one of Sutton Place's most desirable full-service cooperatives.

At Plaza 400, residents enjoy a wide range of amenities, including a brand-new Sky Top Lounge, an outdoor heated rooftop pool with sweeping city views, and a children's playroom - all located on the top floor. Additional features include a fully equipped fitness center with yoga/stretching studio, professional-grade laundry facilities, bicycle storage, and concierge services. A 24-hour doorman, on-site security, and a live-in superintendent and assistant superintendent ensure attentive service and peace of mind.

The building is pet-friendly and permits pieds-à-terre, co-purchasing, guarantors, and parents purchasing for children. Monthly maintenance includes all utilities.

Conveniently located near dining, shopping, parks, and multiple transportation options, Plaza 400 offers a refined and service-oriented lifestyle in one of Manhattan's most established neighborhoods.
