About This Property
Residential conversion will be considered with board approval
An exceptional opportunity to establish or expand your medical practice at one of the Upper East Side's most prestigious addresses. Encompassing approximately 2,000 square feet, this exceptionally versatile first-floor medical suite at 33 East 70th Street offers a discreet, private entrance, thoughtfully-designed clinical layout, generous proportions, and an enviable Madison Avenue location.
The well-configured floor plan features three exposures and a comprehensive array of medical facilities, including two operating rooms, two operatories, a dedicated laboratory, two private offices, and a separate office/consultation room. The clinical spaces are complemented by an expansive central hall, reception area, and a generously proportioned waiting room measuring approximately with a southern exposure overlooking East 70th Street. Three bathrooms, including a full bath adjoining the primary office, along with a dedicated kitchenette, provide additional convenience for practitioners, staff, and patients.
The offering is further enhanced by substantial storage accommodations, including a large storage room accessible through the building's lobby, as well as a separate windowed storage room with plumbing, available as an option and potentially for separate purchase.
Ideally situated on the most sought-after stretch of Madison Avenue, 33 East 70th Street is a distinguished white-glove cooperative built in 1928 by celebrated architects Schwartz & Gross. This is a rare opportunity to acquire a substantial, highly functional medical office in an established Upper East Side location, combining the prestige of a coveted Manhattan address with an existing infrastructure ideally suited to a sophisticated medical practice.
50% financing permitted, 2% flip tax paid by purchaser.
Agent's Note
From Curtis Bain. Details about the apartment are drawn from the listing information provided through RLS by Brown Harris Stevens Residential Sales LLC.
The first floor holds a clinical core of operating rooms, operatories, a laboratory, private offices and a consultation room, all reached from one central hall. A reception area and a waiting room sit alongside those rooms, so patients and staff move through the suite without crossing the practice areas.
The suite has three exposures, and the listing specifies a southern exposure over East 70th Street. A south-facing window can get direct sun for about 8.5 hours on the winter solstice, from 7:41 AM to 4:07 PM, and about 10 hours around the spring and fall equinoxes. Nearby buildings can block some of that sun, so it's worth seeing the windows at different times of day.
A kitchenette and a full bath next to the primary office give the suite a practical setup for a working day. The listing also describes a large storage room reached from the lobby, plus a separate windowed storage room with plumbing that is available as an option, which I like for a clinical space that needs supply room.
Built in 1928 by Schwartz & Gross, 33 East 70th is a co-op on Madison Avenue. Central Park is about 3 minutes away on foot, and the 68 St-Hunter College station on the 6 line is about 5 minutes. Because this is a co-op, a purchase goes through board review, and the listing notes that a residential conversion would be considered with board approval, so it's worth raising that with your broker or an attorney early.
