56 E 87Th St

This is a six-story, 1923-built Beaux-Arts elevator co-op in Carnegie Hill, presenting a boutique residential scale with 13 units that reflect pre-war proportions and finishes. The limestone-and-brick façade and a modest, marble-and-terrazzo lobby convey period character; inside many apartments retain high ceilings, crown moldings, hardwood floors and generous window openings that draw treetop and city views. Typical unit plans emphasize two-bedroom footprints with formal living and dining rooms, separate kitchens (many windowed), multiple closets and den or pantry spaces; several units have been renovated to include modern stainless appliances, in-unit washers/dryers and updated baths while preserving vintage details. Shared building features are intentionally low-key: a planted courtyard garden, bike room, central laundry, deeded storage units in the basement, a part-time superintendent and video intercom entry. The co-op operates without a full-time doorman; management is oriented toward efficient, neighborhood-focused service. Pet ownership is allowed with board approval. Located between Park and Madison Avenues, the building sits a block from Central Park and Museum Mile and within walking distance of multiple subway lines, neighborhood groceries, restaurants and cultural institutions, supporting a walkable Upper East Side lifestyle.
