Description

Flatiron Penthouse Loft with Private Roof Deck and Incredible Views Welcome to this bright and airy 3-bedroom, 2-bath duplex loft perched atop a boutique co-op in the heart of the Flatiron District. This unique penthouse offers downtown views and stunning sunsets through oversized, 7-foot-tall windows in the expansive living room. The crown jewel, a massive private roof deck with panoramic, 360-degree views of Manhattan. With 10'4"ceilings on the main level, the home feels open and spacious. The primary suite features a skylit en-suite bathroom and generous built-out closets with 7'7" upper level ceiling heights. Additional highlights include in-unit washer/dryer, individually controlled heating and A/C (Friedrich units and Mitsubishi Split systems), individually controlled baseboard heating, keyed elevator entry, and a voice intercom system. Plus, three flexible bonus areas are ideal for a home office, study space, or creative studio. Located in the historic Ladies Mile District at the southern edge of Flatiron—just one block from Union Square—you’re surrounded by the best of downtown living. Chelsea, Greenwich Village, West Village, and Gramercy are all within walking distance. Major subway lines and the NJ PATH are moments away, offering easy access to the rest of the city and beyond. This intimate, pet-friendly co-op features 12 stories with only two residences per floor (three on the penthouse level) and a largely owner-occupied community with a liberal sublet policy.
