A six-floor mansion on the “Gold Coast” of Manhattan’s Upper East Side has just been listed for $US50 million.

The home, at 7 East 76th Street, is chock-full of secrets and amenities spread across its 14,000 square feet. Among its 20 rooms are a wine cellar, maid’s quarters, two art galleries, a recreation room, and a sunny solarium.

The property is being sold by Japanese billionaire philanthropist Bungo Shimada, according to the Wall Street Journal. Shimada told the Journal that maintaining the home in “top form” requires too much effort for his lifestyle. Stan Ponte of Sotheby’s International Realty has the listing.
