A rare opportunity to own an extraordinary full-floor, approximately 3,000-square-foot duplex at 52 East End Avenue. Offering five bedrooms, three-and-a-half bathrooms, four private balconies, and multiple exposures, Residence 10ABC combines the scale and privacy of a townhouse with the services and convenience of a white-glove Upper East Side condominium. A private elevator landing opens directly into this expansive home, where oversized windows and multiple exposures fill the residence with natural light and frame open city and river views. At the heart of the home is the recently renovated, oversized chef's kitchen, designed equally for everyday living and large-scale entertaining. The bright corner kitchen enjoys southern and eastern exposures and features extensive white custom cabinetry, glass-front display cabinets, dark stone countertops, a glass-tile backsplash, and exceptional storage and prep space. High-end appliances include Sub-Zero refrigeration, a six-burner Wolf gas range with vented hood, wall ovens, and Miele and Bosch dishwashers. A generous open dining area allows the kitchen to function as a true gathering space for the home. The sprawling corner living room is surrounded by windows and offers exceptional proportions for multiple seating and entertaining areas. Custom built-ins provide additional storage and display space, while direct access to a private balcony extends the living space outdoors. Four generously proportioned bedrooms are located on the main level, allowing for tremendous flexibility for guests, a home office, library, or den. Several bedrooms enjoy their own balcony access, while custom built-ins and abundant storage are found throughout the residence. Two full bathrooms and a powder room complete this level. Occupying the upper level is an exceptionally private corner primary suite, creating a true retreat separate from the rest of the home. The suite features multiple exposures, its own private balcony, extensive custom closet space, and a spacious en-suite marble bathroom with separate soaking tub and shower. Additional features include four private balconies, three-and-a-half bathrooms, hardwood and imported slate flooring, through-the-wall thermostat-controlled air conditioning, a full-size vented washer and dryer, custom millwork and built-ins, French and pocket doors, a mudroom with additional storage, and Lutron lighting controls. With approximately 3,000 square feet spread across two levels, five true bedrooms, exceptional entertaining space, abundant natural light, multiple outdoor spaces, and a private elevator landing, Residence 10ABC offers a scale and versatility rarely found in a Manhattan condominium. Located on a quiet, residential stretch of East End Avenue, moments from Carl Schurz Park, the East River Esplanade, neighborhood restaurants, shops, schools, and transportation, this remarkable residence offers an exceptional combination of space, privacy, and Upper East Side living.
