Spectacular One-Bedroom Penthouse with Maginificent Private Terrace: Rarely does a home combine exceptional outdoor space, sweeping Hudson River and Riverside Park views, and authentic pre-war character quite like this remarkable 17th-floor penthouse at 440 West End Avenue. Occupying the building's entire southwest corner at West 81st Street, this beautifully renovated one-bedroom residence features an extraordinary wraparound terrace of nearly 700 square feet. Lushly planted and furnished with multiple seating and dining areas, the terrace is a private oasis in the sky - perfect for entertaining, dining al fresco, gardening, or simply watching spectacular sunsets over Riverside Park and the Hudson River. Inside, the gracious pre-war details have been beautifully preserved and seamlessly integrated with modern comforts. The open-concept home boasts 10-foot ceilings, oversized windows, original herringbone solid-wood floors, central air conditioning, and a wood-burning fireplace with a honed gray marble mantel. The stunning chef's kitchen is both sophisticated and inviting, with an original tin ceiling, expansive window overlooking the terrace, custom cabinetry, stainless-steel appliances, quartz countertops, and a large center island. The spacious primary bedroom suite offers multiple built-ins, two oversized closets, and a luxurious en-suite windowed bathroom with honed granite floors, frosted glass tile, and a large glass-enclosed shower. An additional oversized walk-in closet is perfect for additional storage. Recent building improvements include repointed exterior walls, a newly replaced roof, and new terrace pavers. Built in 1928 and designed by Schwartz and Gross, 440 West End Avenue is a full-service, 24-hour doorman cooperative with a live-in superintendent. Ideally located in the heart of the Upper West Side, the building is moments from Riverside Park, Broadway's shops and restaurants, Zabar's, the 79th Street subway station, and crosstown transportation. A rare opportunity to own a sophisticated Upper West Side penthouse with an extraordinary private terrace, breathtaking river and park views, and the timeless character of a classic pre-war home. Showings begin on September 8th.
