A historical neo-Italian Renaissance carriage house built in 1910 and later transformed<\/a> into a spectacular residence by former Morgan Stanley CEO John Mack and his wife, Christy, has just hit the market in Manhattan for an astonishing $80 million.<\/p>\n

The Upper East Side estate once served as a garage and chauffeur’s quarters for Singer heir Stephen C. Clark and was later used by Paul and Bunny Mellon as a private garage. The Macks purchased the 15,978-square-foot structure for $13.5 million in 2009 and transformed it into a 20-room residence in 2011.<\/p>\n

A “no-expense-spared renovation” now features quarter-sawn oak floors, custom wallpapers, bespoke drapery and fabrics, and designer lighting. The lavish residence has climbed its way to the top spot on the week’s most expensive homes list<\/a>.<\/p>\n

Luxurious amenities include security and staff offices, a 13-seat soundproof theater, a one-car garage doubling as entertainment space, private guest quarters with a full kitchen, and a chef’s kitchen with walk-out dining terrace.<\/p>\n

Other highlights include six fireplaces, a wood-paneled library, a primary suite with dual dressing rooms and marble baths, two soundproof offices, a 6,319-bottle wine cellar with prep kitchen, and a rooftop terrace to enjoy the city views.<\/p>\n

Wellness amenities on the lower level offer a cold plunge, steam room, sauna, massage room, and a full gym.<\/p>\n

More spectacular estates to make the week’s most expensive homes list include a brand-new mansion on Nantucket, MA<\/a>, a 48.2-acre Greenwich, CT,<\/a> estate, and a recently built Washington<\/a> residence overlooking Lake Washington.<\/p>\n
