It’s springtime, the season for lovers, and Macklowe Properties’ 737 Park Avenue has proven quite crush-worthy. This 20-story, 60-unit pre-war condominium, located on the northeast corner of 71st Street and Park Avenue, has been completely revamped. Handel Architects and Moed de Armas & Shannon have transformed the condominium into a study in perfection. Residences range from three- to five- bedrooms with rich amenities, including a 24-hour doorman, elevator operators, a resident manager, fitness center, children’s playroom, a garden room for entertaining, private storage and storage for bicycles and strollers.
