A SoHo Penthouse with a Private Rooftop Terrace Just Under 1,000 SF and 100 Feet of Frontage on Coveted Greene Street. Perched atop a 19th-century former silk showroom in the Cast Iron Historic District, Penthouse A at 63 Greene Street is a one-of-a-kind 4-bedroom, 4-bathroom duplex that combines rich architectural history with luxurious modern living. Spanning nearly 3,600 square feet with a rare 100 feet of frontage along coveted cobblestoned Greene Street, this grand-scale home is capped by a spectacular private rooftop terrace measuring over 1,000 square feet-ideal for entertaining, sunbathing, or serene alfresco dining under the skyline. This is the largest residence in the building and a true full-floor home, wrapped in light from oversized sash windows and defined by 12-foot barrel-vaulted redbrick ceilings, exposed ducts, and cast-iron columns. The dramatic great room features an open-plan living and dining space anchored by a floating steel and glass staircase and chef's kitchen with a massive waterfall island, custom cabinetry, mosaic backsplash, and premium appliances from Bertazzoni and Sub-Zero. The king-size primary suite offers a wall of custom closets and a spa-like bath with floating double vanity and walk-in rainfall shower. Two additional bedrooms enjoy full en-suite baths and deep soaking tubs, while a fourth bedroom off the living area makes an ideal home office, playroom, or den. Additional highlights include radiant heated bathroom floors with Lefroy Brooks fixtures, wide-plank hardwood flooring, multi-zone central air, and in-unit laundry by Miele. 63 Greene Street offers part-time doorman service, bicycle storage, a package room, and a beautifully landscaped communal rooftop. Located moments from SoHo's finest-Sadelle's, Balthazar, Dominique Ansel-and close to Little Italy, Tribeca, and the West Village, with easy access to the C, E, F, R, W, and 6 trains. Pets are welcome.
