The 44-year-old former playboy claims that he intends the 8,400-square-foot home as a kind of grand diplomat’s hostel, as well as a place for family life with his wife, the Brazilian model Amanda Zampolli (nee Ungaro), and the couple’s 4-year-old son, Giovanni. (That the house made intermittent appearances on the market through March of this year, asking $22.5 million for the renovated product—and that an enormous banner reading “A Paolo Zampolli Development” hangs over its door—suggests some flexibility in the plan.)
