A truly rare offering on one of the most coveted blocks of the Upper East Side, 62nd Street between Fifth and Madison. This exceptional Astor-era townhouse delivers the scale, elegance, and privacy of a historic mansion, paired with the white-glove services typically reserved for premier full-service buildings. It is an almost unheard-of combination at this level. Originally built as a Gilded Age residence, the property has been meticulously restored and fully modernized, blending classic architectural grandeur with contemporary refinement. Soaring ceiling heights, grandly proportioned rooms, and oversized windows define the interiors, creating an atmosphere of drama, light, and timeless sophistication. The building is currently configured as a free-market multifamily with three residences, an intimate boutique setup that offers flexibility for an end user, investor, or legacy buyer. Throughout, the property showcases beautifully executed craftsmanship, including rich hardwood floors, marble-lined halls and baths, decorative fireplaces, and thoughtfully preserved prewar architectural details. State-of-the-art systems have been seamlessly integrated, including multi-zoned Mitsubishi heating and cooling with concierge and remote access. Additional conveniences include an in-building washer and dryer for each residence, premium finishes, and a solid wood custom kitchen design equipped for top-tier appliances such as Sub-Zero, Wolf, and Miele. For the buyer seeking a singular home in the heart of the Upper East Side, the existing configuration also presents a compelling single-family vision. It is an opportunity to reimagine the townhouse as one grand private residence with the volume, presence, and pedigree rarely available this close to Fifth Avenue and Central Park. The building benefits from full-time doorman service, offering privacy, security, and a level of personal attention rarely found in properties of this intimate scale. Many rooms enjoy picturesque views of the surrounding Beaux-Arts architecture that defines this storied block. Located just half a block from Central Park and moments from Bergdorf Goodman, The Plaza, and the finest boutiques and restaurants along Madison Avenue, this is an extraordinary opportunity to acquire a free-market multifamily townhouse with future single-family potential on one of Manhattan's most prestigious residential streets.
