An Entire Floor. An Exceptional Way To Live. A Private Estate Above the Upper West Side In a city defined by extraordinary architecture, true residential grandeur is increasingly rare. Occupying the entire fifteenth floor of 535 West End Avenue, this approximately 8,451-square-foot residence offers the privacy and proportions of a private estate with the sophistication of Manhattan condominium living. Seven bedrooms, seven-and-a-half bathrooms, four exposures and a private elevator landing create a home of uncommon scale. The Architecture of Space Arrival begins in an expansive, approximately 30-foot-wide gallery, introducing a thoughtful sequence of beautifully proportioned rooms. Coffered ceilings, fine millwork, hardwood floors and oversized windows lend depth, warmth and natural light. Grand living and dining rooms accommodate intimate evenings or large-scale entertaining. A Brazilian marble-framed fireplace anchors the living room; nearby, a corner library with arched windows, illuminated custom shelving and a second fireplace offers a quieter retreat. Where Design Meets Daily Life The Smallbone kitchen features tailored cabinetry, polished granite countertops, a generous center island and appliances by La Cornue, Miele and Sub-Zero. An adjoining pantry, wet bar and family room make everyday living and entertaining equally effortless. The Luxury of Privacy The primary suite is a sanctuary of its own, with a sitting room, expansive walk-through dressing room and two separate bathrooms. Six additional bedrooms offer exceptional flexibility for family, guests and work. A dedicated laundry room and abundant storage complete the residence. A Distinguished Manhattan Address Residents enjoy an indoor pool, fitness center, library, catering and private entertaining room, billiards lounge, golf simulator and landscaped courtyard, together with full-time doorman service and a resident manager. Riverside Park, Central Park and the Upper West Side's celebrated cultural and dining destinations are close at hand. A deeded parking space in the building's private garage, with direct elevator access into the building, is available for separate purchase. An uncommon offering, defined by architecture, privacy and a sense of permanence. Capital Assessment: A monthly capital assessment of $2,068.14 is in effect through December 2026, primarily for the expansion of the resident manager's unit.
