Description
The Chelsea Mansion
A rare and remarkable Seminary Block mansion, 436 West 20th Street dates to 1835 and occupies land once owned by Clement Clarke Moore, author of "'Twas the Night Before Christmas." Fully gut renovated while preserving the grandeur of its historic setting, this approximately 10,160-square-foot, 25-foot-wide residence unfolds across six levels as an exceptional single-family home in the heart of Chelsea.
Known as The Chelsea Mansion, the property combines the scale and architectural presence of a 19th-century townhouse with the sophistication and precision of contemporary design. Seven bedrooms, eight full bathrooms, three powder rooms, eight fireplaces, and a new state-of-the-art elevator are complemented by five private outdoor spaces, including a landscaped garden, two terraces, and two balconies.
Directly opposite The General Theological Seminary and moments from the High Line, Chelsea Market, Little Island, the Meatpacking District, galleries, restaurants, and nightlife, the location is quintessentially Chelsea.
The interiors are defined by generous proportions, natural light, and carefully considered craftsmanship. Lutron lighting, oak floors, radiant-heated bathrooms, custom millwork, and a sophisticated HVAC system with heating, cooling, and humidification controls are seamlessly integrated throughout.
The parlor level is distinguished by a grand entertaining space with nearly 12-foot ceilings, two fireplaces, and a separate dining area. A private guest suite or study with en-suite bath completes the floor.
At garden level, an exceptional chef's kitchen anchors the home, finished in custom walnut with stone surfaces, an oversized waterfall island, and premium appliances including a Viking Tuscany Pro range, Gaggenau refrigerator, and oversized Sub-Zero wine refrigerator. The kitchen opens directly to the private garden, creating a natural extension of the entertaining spaces. A garden room, full bath, windowed laundry room, and cellar complete the level.
The third floor is dedicated to the primary suite and private living spaces. A generous sitting area with walnut wet bar and fireplace leads to a stately library and beautifully appointed en-suite bath. A private balcony overlooks the garden, while a separate office and dressing area and an additional full bath provide flexibility and discretion.
Three additional en-suite bedrooms occupy the fourth floor, each with walk-in closets and abundant natural light. A working fireplace distinguishes the front bedroom, while the rear bedroom enjoys direct access to a private balcony.
The fifth and sixth floors culminate in an extraordinary private entertaining level. Vaulted double-height ceilings, expansive skylights, a fireplace, two terraces, and a separate loft create an elevated retreat with a rare sense of volume and privacy.
The Chelsea Mansion is an exceptional expression of historic Manhattan architecture reinterpreted for contemporary living-distinguished by its width, scale, craftsmanship, provenance, and extraordinary collection of private outdoor spaces. It is a singular residence in one of New York's most coveted neighborhoods.
