Producers Chris and Roberta Hanley are known for their innovative film projects, including cult-hit American Psycho and Sofia Coppola’s directorial debut, The Virgin Suicides. Before his film career, Chris also worked in art, dealing in pieces by such luminaries as Andy Warhol and Jean-Michel Basquiat. When it came time for the couple to design a house, they once again wanted something cutting-edge. The Hanleys partnered with architect Tomas Orsinski, a Frank Gehry collaborator, to design their one-of-a-kind Invisible House, situated in Joshua Tree, California. The striking home has now been listed for sale at $18 million.
