Architect Marvin Mitchell has bought Frank Sinatra's former penthouse at the Edgewater building on 530 E. 72nd Street for a cool $4.995 million.

Mitchell — who told The Wall Street Journal that he purchased the home for its spacious floorplan, not its history — takes ownership of the 3,200-square-foot, tri-level apartment just four years after the previous owner, Long Island car insurance executive Penny Hart, renovated it. Hart, who bought the home for a reported $2.5 million and never lived in it, first listed it at $7.7 million in 2012.
