Designed by renowned architect William Lescaze, a pioneer of the European International Style, this landmark townhouse offers a rare opportunity to own a piece of modernist history in Manhattan’s prestigious Upper East Side. Spanning over 7,000 square feet across five floors, the property is currently configured as three elegant duplex residences, each with private outdoor space, keyed elevator access, and high-end finishes. The home has undergone a meticulous renovation, seamlessly blending its original mid-century design with contemporary luxury. Features include Viking kitchens, Sonos sound systems, central air and vacuum systems, and in-unit laundry. A large elevator services all floors, enhancing accessibility and convenience. Each floor boasts terraces with city views, and the landscaped roof deck and garden courtyard offer serene outdoor retreats. The flexible layout supports multigenerational living, investment income, or conversion to a grand single-family or two-family residence. Located just steps from Central Park, the Guggenheim, and the Metropolitan Museum of Art, the property is surrounded by world-class dining, boutique shopping, and top-tier schools including P.S. 6 and The Dalton School. With multiple nearby bus routes and proximity to Madison Avenue, the location offers unmatched access to culture, commerce, and community.
