308 East 79th Street – Unit 1B offers a rare opportunity to acquire a flexible ground-floor commercial co-op in the heart of the Upper East Side. Located within a well-maintained pre-war cooperative, the space is currently configured as a medical office, ideal for professional, wellness, therapy, consulting, boutique office, or owner-user use. The unit features direct ground-floor access and excellent neighborhood convenience surrounded by dense residential population, luxury housing, established retail, and dining. Positioned just moments from major transportation, the property benefits from excellent accessibility within one of Manhattan’s most stable and affluent submarkets. A key value-add opportunity is the co-op’s allowance for residential conversion, subject to co-op approval and applicable regulations. This provides exceptional flexibility for investors, live-work users, or end-users seeking long-term optionality in a supply- constrained Upper East Side market.
