635/641 Avenue of the Americas, New York, NY

635/641 Avenue of the Americas is conveniently located in the heart of Chelsea between 19th and 20th Streets. Once home to the Simpson Crawford Department Store, the buildings have recently been redeveloped into a Class "A" office building featuring a brand new lobby, elevators, state-of-the-art building systems and a one-of-a-kind penthouse rooftop that highlights a bocce court and event space. Completed in 2015, the building is now considered one of the most desirable office properties in its sub-market.
