Perched atop The Glassworks - a distinguished boutique prewar building circa 1896, converted to condominiums in 2003 - this extraordinary Chelsea penthouse duplex spans over 3,600 square feet of beautifully appointed living space, offering a rare combination of historic character, modern luxury, and remarkable versatility. The main level is anchored by a spectacular open kitchen featuring a large island with seating, top-of-the-line stainless steel appliances, a six-burner stove with grill and professional venting, and a wine refrigerator - a true chef's haven. The kitchen opens to a generous dining area, which flows seamlessly into a sun-flooded living room with oversized windows. A conveniently located powder room off the kitchen offers the potential to enlarge. Rich pre-war wooden beams and hardwood floors throughout speak to the building's storied character. The primary bedroom is a serene retreat, complete with a private en-suite bath and direct access to a private balcony. A well-appointed hall bath serves the additional bedrooms. All bathrooms feature stylish wood and tile finishes. An in-unit washer/dryer adds everyday convenience. Upstairs, a vast and wonderfully flexible space currently serves as a den and children's playroom -- equally suited as an art studio, home office, media room, or additional sleeping quarters. This level opens to two large decks: one beautifully finished with wood floors, lush planters, and seating for eight or more, and a second unfinished deck offering tremendous potential. Rare air rights present an extraordinary opportunity to expand and further customize this already exceptional residence. The Glassworks offers key-locked elevator access, an exceptionally attentive superintendent, and a beautifully renovated lobby. With 90% financing permitted and low monthly carrying costs, this is an outstanding value for a penthouse of this scale and distinction. Ideally situated in the heart of Chelsea, the building is surrounded by acclaimed restaurants, world-class galleries, and cultural destinations, with Whole Foods and Trader Joe's just blocks away and excellent transportation options at your doorstep.
