With private elevator access to both floors, open river and skyline views, and complete separation from neighbors, this home offers unmatched privacy, volume, and flexibility - all it takes to connect them is one staircase. Penthouse 9 is a stunning 3-bedroom, 2.5-bath home anchored by a dramatic 50-foot-wide great room with floor-to-ceiling windows and a 720 SF terrace spanning the entire width of the building. The open kitchen is finished with custom cabinetry, Montclair Danby marble, and top-tier appliances. The primary suite features a second private terrace and a luxurious spa bath with radiant heated floors. Penthouse 10, directly above, offers four more bedrooms, two additional terraces, and a second 50-foot-wide entertaining space with open exposures and incredible light - perfect for a formal living room, media lounge, or family retreat. Every inch of both homes is fully finished and in mint condition, with smart home wiring, radiant heat, wide-plank floors, and generous proportions throughout. No renovation needed - just add stairs and move in. Gracie Green is a boutique, full-service condominium offering an attended lobby, fitness center, roof lounge, children's playroom, storage, and bike room. Located near Carl Schurz Park, the East River Esplanade, Asphalt Green, and the Q/4/5/6 trains.
