This gigantic three-penthouse combo is owned by the celebrity photographer Ken Nahoum, who’s captured everyone from Robert De Niro to Michael Douglas to Dr. Dre to Johnny Cash. According to Mansion Global, he began living in the cast iron SoHo building, 95 Greene Street, in the 1980s after it was converted to residential use. In 1999, he bought up a 1,231-square-foot apartment here with his now ex-girlfriend, Victoria’s Secret model Basia Milewicz. Then in 2002, he bought the two adjacent penthouses and the rooftop section. Now it’s a massive showpiece penthouse, with 8,200 square feet of interior living space alongside five outdoor terraces totaling 4,000 square feet.
