Former Morgan Stanley CEO’s $13.5m Manhattan mansion now lists for $80m

Former Morgan Stanley CEO John Mack and his wife, Christy, have listed their palatial home at 165 East 70th Street, according to a report by The Wall Street Journal. The historic neo-Italian Renaissance carriage house, built in 1910 and later transformed into a spectacular residence by the couple, is asking $80 million. If it fetches the asking price, it would become the priciest residential townhouse ever sold in New York City. The Macks purchased the 15,978-square-foot residence in 2009 for $13.5 million and transformed it into a 20-room home by 2011.A carriage house built in 1910In 1902, banker Henri Wertheim hired architect C.P.H.
