Positioned along one of Manhattan’s most prestigious corridors, 905 Fifth Ave, Unit 1AD offers a rare opportunity to acquire a turnkey office cooperative directly across from Central Park at the highly sought-after corner of Fifth Avenue and East 72nd St. This ground-floor corner unit features private street-level access along Fifth Avenue, complemented by a secondary entrance through a white-glove residential lobby, providing an ideal combination of visibility, accessibility, and discretion for both practitioners and patients. The space is fully built out for medical use and configured with four exam rooms, including a surgical room, two private offices, a reception and waiting area, kitchenette, changing room, and two restrooms. The existing layout supports immediate occupancy while offering flexibility for a wide range of specialties. Recently renovated and equipped with central air conditioning, the unit is move-in ready and designed for efficient day-to-day operations. The layout prioritizes workflow, patient experience, and functional separation between clinical and administrative areas. Located within a full-service cooperative with a 24-hour doorman, elevator, and resident manager, the property combines institutional-quality infrastructure with the prestige of a Fifth Avenue address. The property benefits from immediate proximity to leading medical institutions, including Lenox Hill Hospital, Mount Sinai, and NewYork-Presbyterian / Weill Cornell, reinforcing its positioning as a premier destination for established practices or groups seeking an Upper East Side flagship location. With direct Central Park exposure, strong foot traffic, and limited availability of comparable medical spaces along Fifth Avenue, Unit 1AD represents a compelling acquisition opportunity in one of Manhattan’s most supply-constrained and high-barrier-to-entry submarkets. Cooperative Details: Purchaser to pay 3% flip tax. Financing permitted up to 33%. Cooperative board approval required.
