55 E 65Th St

A landmarked prewar co-operative on Manhattan’s Upper East Side, this seven-story, early 20th-century residence was built in 1910 and retains classic architectural proportions across its small, boutique scale. The property contains under 40 units and presents a mix of renovated one-bedroom layouts and duplexes that keep period details — high ceilings, crown moldings, chandeliers, hardwood floors and working wood-burning fireplaces — alongside contemporary kitchen and bath upgrades. Common areas are quietly appointed: an elevator, live-in superintendent, renovated hallways, on-site laundry, individual storage and bicycle storage. Many apartments feature built-ins, generous closet walls and modest private outdoor spaces. The building is wholly shareholder-owned and operates as a cooperative with a friendly pet policy and pied-à-terre allowance; some apartments have financing limitations and occasional assessments. Located on a tree-lined block between Madison and Park Avenues, the residence sits steps from Madison Avenue shopping, restaurants, and Central Park, offering a compact, maintenance-managed living experience in an established historic neighborhood.
