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. ## Property Details - **Property Type**: Single Family Residence - **Beds**: 7 - **Baths**: 8 - **Rooms**: 14 - **Sqft**: 10,160 sqft - **Stories**: 5 - **Year Built**: 1910 - **Price per Sqft**: $2,953 - **Monthly Taxes**: $65,954 / mo - **Listed On**: Oct 13, 2026 - **Days on Market**: 1 Days ### Residence Features - Central Air - Building Other - Washer Hookup - In Unit - Garden - Private Outdoor Space Over 60 Sqft - Smoke Free - Walk-In Closet(s) - Dishwasher - Washer Dryer Allowed ## Estimated Monthly Payment **$217,650 / month**, assuming a 20% down payment ($6,000,000), a 6.5% interest rate and a 30-year term.

Those are excluded from the benchmark below. ### How this price compares - **This home**: $30,000,000 - **Median sold price**: $5,900,000 - **Difference**: +$24,100,000 (+408.5%) - **This home, $/ft²**: $2,953 - **Median $/ft²**: $1,436 - **Comparable sales**: 15 - **Sales from**: November 2021 – September 2026 - **Middle half of those sales**: $5,295,500 – $9,950,000 Based on house sales in Chelsea.

Sample sizes vary by metric. These are two separate periods measured on different clocks — time to find a buyer, and time from agreed deal to closing. They are medians of different sets of sales and do not add together into a single "days on market" figure. Sales data through September 2026. Sale prices are the consideration recorded with the City in ACRIS, and each sale is dated by the day the City recorded it. A closing date reported to the MLS typically falls one to two weeks earlier. Recorded sales describe what has already happened and are not an appraisal, a valuation, or an estimate of what this home will sell for.

We calculated the tax for those years using the prior year’s rate, so treat them as an estimate rather than a figure the City has adopted. Every rate without the Estimated marker is the published one. Tax Assessment is the assessed value on the City’s roll, and it is the figure other listing sites publish. It is not what the bill is calculated on. New York phases assessment changes in gradually for some tax classes, so the City bills the Billable Value shown beside it, less any exemption the owner holds. It usually trails the assessment, and it can sit above it for a few years after an assessment falls. Figures are the New York City Department of Finance assessment roll for tax lot 1007170062. Assessed and billable values are determined by the City for tax purposes and are not an appraisal or an estimate of market value. Tax classes and rates are set annually and can change.
