40 E 88Th St

Built in 1930, this 15-story prewar cooperative on Madison Avenue anchors the crest of Carnegie Hill with a restored Art Deco lobby and classic façade. Units are predominantly multi-room residences — Classic 6s, 7s, 8s and full-floor penthouses — that preserve prewar details such as herringbone and oak parquet floors, high beamed ceilings, original moldings, built-in cabinetry and wood-burning fireplaces. Apartment layouts favor long entrance galleries, separate sleeping wings, formal dining rooms, eat-in kitchens with pantry/butler’s areas, plentiful closets and generous ceiling heights; many layouts include a staff or fourth bedroom and built-in storage. Common building features include full-time doorman and concierge, live-in resident manager/superintendent, an attended lobby, elevator service, central laundry room, bike room, transferable private storage cages and a newly equipped fitness center. A selection of homes offers private outdoor terraces or setback roof gardens. The co-op is pet-friendly, permits up to 50% financing in many instances, allows washer/dryers with approval, and enforces typical board controls on sublets and pied-à-terres depending on the apartment. Located one block from Central Park and the Jacqueline Kennedy Onassis Reservoir, the building puts residents steps from Museum Mile, Madison Avenue shops, restaurants, schools and transit, supporting a refined Upper East Side lifestyle centered on culture, green space and formal entertaining.
