    This 25-foot-wide elevator townhouse with 20+ foot ceilings stands as a rare offering - a 9,400-square-foot architectural statement masterfully reconstructed over three years to deliver uncompromising scale, privacy, and sophistication. With commercial and residential zoning, this property is a perfect opportunity for commercial, professional or residential use. Originally built in 1819 and now spanning seven floors, the residence has been meticulously restored and expanded with a reverence for its provenance and an eye toward contemporary living. The result seamlessly integrates heritage architecture with modern engineering and bespoke design. Throughout the residence: • Custom elevator servicing all floors • Original fireplace mantels thoughtfully preserved • Imported marble and stonework • California Faucets fixtures • Extensive bespoke millwork • Advanced mechanical systems discreetly integrated A dramatic entry introduces over 20-foot ceilings and an extraordinary sculptural staircase - a sweeping, curved focal point that anchors the home with quiet grandeur. Custom lighting installations and artisan chandeliers create a gallery-like atmosphere throughout, enhancing the volume and architectural symmetry of each floor. Entertaining unfolds effortlessly across expansive formal and informal spaces. The chef's kitchen is both functional and sculptural, anchored by a hand-forged walnut island and appointed with Gaggenau and Thermador appliances. Custom millwork and imported stone elevate the space to a level befitting a private culinary atelier. The penthouse entertaining level offers a bespoke bar and a dramatic great room designed for curated gatherings, private events, or intimate evenings overlooking the city skyline. The Primary Floor The entire third floor is devoted to the primary suite - an extraordinary private retreat. The Calacatta Gold marble bath evokes a five-star European spa, complete with soaking tub and bespoke fittings. A private terrace extends the suite outdoors, offering a tranquil sanctuary above the city. Rooftop Atrium & Terraces At the crown of the home, a luminous glass atrium opens to dual landscaped roof terraces with sweeping skyline views. This rare indoor-outdoor pavilion offers a level of privacy and perspective seldom found in Manhattan - ideal for sunrise reflections or evening receptions under the city lights. Lower Level Flexibility The full-length lower level, with ceilings exceeding nine feet, functions as a private wellness level, screening room, executive office suite, or independent guest quarters. Its scale and finish rival that of a luxury apartment. This is a property for the buyer who values scale, craftsmanship, privacy, and architectural integrity - all in one of Manhattan's most culturally vibrant and enduring neighborhoods. A true Chelsea legacy residence.
