In 1979, accessories designer Reva Ostrow asked artist and designer Ward Bennett to redesign her Upper East Side apartment. Located in the Rosario Candela-designed 955 Fifth Avenue, Bennett responded by gutting the classic pre-war apartment and transforming it into a stylish, industrial loft with exposed beams, terrazzo floors, stainless-steel accents, and iconic furniture. Over the past 40 years, Ostrow has kept the apartment in pristine “museum-like” condition, with every object still precisely where Bennett placed it. “Hiring him was the best thing I’ve ever done in my life,” she once said. Now, in order to spend more time with her family, Ostrow has placed the one-of-a-kind residence on the market for $4,900,000.
