Former Morgan Stanley CEO’s Historic UES Carriage House Hits the Market for a Record-Breaking $80 Million

There are plenty of historic townhouses scattered throughout Manhattan’s Upper East Side, but how many can say that they’ve housed some of New York’s most influential names in finance and society? Tucked quietly away at 165 East 70th Street, a former carriage house transformed into a private residence comes to market for a stunning $80 million. Now, it is the most expensive townhouse currently on offer in New York City. The sellers are former Morgan Stanley CEO John Mack and his wife, Christy.

Dating back to around 1902, the home was originally designed by C.P.H. Gilbert, a notable Gilded Age architect, for banker Henri P. Wertheim. The original four-story home passed through the hands of several notable New Yorkers. Financier Otto Kahn, who built Oheka Castle on Long Island, spent time at the property, along with Stephen Carlton Clark, a founder of the National Baseball Hall of Fame, and philanthropist Rachel Lambert “Bunny” Mellon. 

Today, the sprawling 16,000-square-foot residence spans six levels, from a cellar all the way up to a solarium. There are a total of 20 rooms spread throughout, with some pretty luxurious amenities. Think, a soundproof theater, a chef’s kitchen, a mahogany-paneled library, and a granite-lined jacuzzi/cold plunge.

“Considering that the property has had just five owners in more than 120 years, a veritable who’s who of New York society and finance, it would be poetic to see that legacy continue with the next owner,” listing agent Mike Fabbri of The Agency told dailyDEEDS. “But ultimately, we’re looking for a buyer who truly appreciates the extraordinary craftsmanship, attention to detail, and quality that have gone into creating this one-of-a-kind home.” 

If the home sells for its asking price, the transaction would reportedly set a new record for a New York City townhouse sale.
