510 E 86Th St

A mid-century, postwar cooperative set on a quiet, tree-lined Upper East Side block, this 21-story building completed in 1959 contains roughly 32 large apartments, many configured as multi-bedroom units and junior four-room plans. The exterior reads as a restrained masonry tower with terraces and occasional river-facing exposures; several residences include private outdoor space. Interiors emphasize loft-like proportions and practical layouts: formal dining rooms, entrance foyers, walk-in closets, wet bars and built-in storage appear often, while many units have updated open living/dining plans and windowed kitchens. Common areas support everyday living with a full-time doorman, live-in superintendent, laundry room, bike and storage rooms, and building-managed maintenance staff. Resident amenities extend to an on-site basketball court and a mix of small private outdoor terraces. The co-op board allows pets (board approval), pied-à-terres in many cases, and permits washer/dryer installation with approval; financing up to 75% is typical and a 2% flip tax applies. Located between York and East End Avenues, the building sits steps from Carl Schurz Park, the East River Promenade, local markets and multiple transit options, offering a neighborhood-oriented, service-backed residential experience.
