PENTHOUSE IN THE SKY Perched atop Madison Green, this extraordinary 3,600 square foot duplex penthouse is one of Flatiron's most compelling residences. Sweeping 270-degree views frame iconic landmarks in every direction - One World Trade to the south, the Flatiron Building at eye level, and the Empire State Building to the north - all visible from 52 windows across two floors. Designed by Wayne Turett, the flowing layout opens from a dramatic entry foyer into expansive living and dining spaces that connect directly to a beautifully landscaped wraparound terrace. With approximately 650SF of private outdoor space - including the terrace and two balconies - this home is equally suited for grand entertaining and everyday living. The chef's kitchen has undergone a complete transformation and features marble countertops, custom cabinetry, and a full suite of premium appliances, including Sub-Zero, WOLF, and Bosch. A grand living room with two wood-burning fireplaces, Brazilian walnut floors, and an adjoining library - easily convertible to a guest suite with its own entrance - completes the upper level. A custom steel-and-wood staircase with integrated storage leads to the private lower level, where five generously scaled bedrooms enjoy the same iconic exposures. The primary suite is a true retreat, offering a private balcony, expansive dressing area, and spa-quality Bisazza-tiled bath with a deep Kohler whirlpool tub beneath a striking picture window. Additional highlights include Somfy motorized shades, Lutron dimmer lighting, extensive built-ins, and a guest powder room. Madison Green is a full-service condominium with a 24-hour doorman, concierge, resident manager, fitness room, and sky-top lounge. Please note some images have been virtually staged.
