Robert Weinstein, who runs Weinstein Company with his brother, Harvey Weinstein, has put his 6,500-square-foot duplex at the Beresford on the market for about $34 million, according to the Observer. Weinstein bought the home, at 211 Central Park West between 81st and 82nd streets, for $20 million in September 2004. The $34 million price tag is more than any unit has ever sold for in the building. Investor Bill Ackman spent $26 million on a duplex one floor above Weinstein’s unit, and Jerry Seinfeld bought a duplex in the building for $4.35 million 10 years ago. Brown Harris Stevens’ Ileen Schoenfeld, who listed the home five years ago when Weinstein bought it, is reportedly representing the unit.
