Residence GA at 500 West End Avenue is a sophisticated four-bedroom duplex that provides the scale and privacy of a townhouse within one of the Upper West Side's most distinguished prewar condominiums. Spanning approximately 2,500 square feet, the residence is defined by a striking wrought iron and brass staircase that serves as a central architectural statement, separating the public entertaining spaces from the private quarters. The upper level is dedicated to a quiet and expansive primary suite, featuring a spa-quality bathroom and an oversized, fully outfitted walk-in dressing room. The lower level contains three additional well-proportioned bedrooms and two full bathrooms, all equipped with radiant heated floors for consistent year-round comfort. Throughout the home, high-end finishes like hardwood flooring and custom storage solutions maintain a standard of understated luxury. The heart of the home is a custom-designed chef's kitchen anchored by marble countertops and a professional-grade appliance suite by Wolf, Sub-Zero, and Fisher & Paykel. Supporting the residence's infrastructure is a two-zoned central air system for precise climate control. This layout is specifically engineered for a buyer seeking a long-term family residence or a high-value asset that prioritizes both form and function. Located at the corner of West End Avenue and 84th Street, 500 West End Avenue is a full-service condominium offering a 24-hour doorman, live-in superintendent, and storage. Situated moments from Riverside Park and the neighborhood's premier dining and transportation, this property represents a rare opportunity to secure a large-scale, versatile residence in a blue-chip Manhattan location.
