Located in a prime Upper East Side location, this spacious professional unit at 440 East 79th Street, 1D offers an exceptional opportunity in a well-run, full-service cooperative. Currently configured as a dental office, the space features two exam rooms, a comfortable reception area, and a private office, all laid out efficiently for medical or professional use. The unit benefits from two separate entrances—one directly from the street and another through the building lobby—providing flexibility, convenience, and discretion. The cooperative is impeccably maintained with full-service amenities, and the apartment offers excellent potential for future use. With board approval, there is a possibility to convert the space into a one-bedroom residence, making this a versatile opportunity for end users or investors seeking flexibility in one of Manhattan’s most desirable neighborhoods.
