Wrapped by an expansive terrace with sweeping Hudson River and open city views, this one-bedroom penthouse offers a rare opportunity to own a truly special Upper West Side residence. Set atop a distinguished prewar cooperative, the home blends timeless architectural character with exceptional indoor-outdoor living. Interior details include soaring beamed ceilings reaching approximately 10 feet, classic herringbone hardwood floors, a wood-burning fireplace, and beautifully windowed kitchen and bath spaces that fill the apartment with natural light throughout the day. The terrace is the centerpiece of the home - an extraordinary extension of the living space with multiple areas for dining, relaxing, entertaining, and gardening, all framed by dramatic skyline and river views. From sunrise over the city to glowing sunsets across the Hudson, the setting is remarkable at every hour. A washer/dryer may also be installed with board approval, offering additional convenience and flexibility for future ownership. 440 West End Avenue is an intimate full-service cooperative with just 91 residences. Residents enjoy a full-time doorman, resident manager, landscaped roof deck, laundry room, bicycle storage, and playroom. Perfectly positioned at the corner of West End Avenue and 81st Street, the building is moments from Riverside Park, Central Park, Lincoln Center, the Museum of Natural History, Zabar's, and some of the neighborhood's best dining and shopping, with easy access to transportation nearby.
