For decades home to the celebrated Mnuchin Gallery, 45 East 78th Street now can present itself again as a private residence or commercial art gallery of the highest order. Six magnificent stories with private elevator service throughout, this 33’ 4” wide mansion offers approximately 17,600 square feet of extraordinary volume across meticulously proportioned floors. Every detail speaks to a grandeur that is increasingly impossible to find in New York City. Guests enter on the first floor into a beautiful and gracious entry gallery — a statement of arrival that immediately sets the tone. Adjacent to the double-door entry is what can be an elegant entertaining or dining gallery, perfect for large-scale receptions or intimate dinners. The kitchen on this level connects seamlessly to the floors above via a private staircase, which can facilitate entertaining. The parlor floor is the social heart of this residence. Here, a dramatic circular staircase — a sculptural centerpiece — anchors a floor of sweeping, light-filled spaces. Two large formal entertaining spaces command each end of the property, each with fireplaces. These rooms, with their soaring ceilings and landmarked architectural detailing, are simply irreplaceable in today's market. The entire third and fourth floors present well-proportioned rooms, offering flexibility for your desired use. Throughout the home, four full bathrooms and five powder rooms serve each floor with ease and discretion. The crown of this exceptional residence is a 1,335-square-foot private rooftop terrace — a sky-high sanctuary above the Upper East Side roofline with direct elevator access. This floor is equipped with a full guest suite including a bedroom, kitchenette and full bathroom. The garden level offers tall ceilings and oversized windows overlooking a north-facing courtyard. The mansion dates to the early 1900s and, as a designated landmark, has retained its grand yet domestic character. Situated on East 78th Street between Madison and Park Avenues, the address places residents moments from Central Park, world-class museums, and the finest restaurants and boutiques the Upper East Side has to offer. A property of this caliber comes to market once in a lifetime. ## Property Details - **Property Type**: Single Family Residence - **Beds**: 9 - **Total Baths**: 9 - **Rooms**: 18 - **Sqft**: 17,600 sqft - **Stories**: 5 - **Year Built**: 1913 - **Price per Sqft**: $1,989 - **Monthly Taxes**: $32,158 / mo - **Listed On**: May 19, 2026 - **Days on Market**: 116 Days ### Residence Features - In Unit - Private Outdoor Space Over 60 Sqft ## Sales Evidence ### How this price compares The median closed price for comparable house sales in Upper East Side is $10,750,000, based on 29 sales between September 2021 and July 2026. This home is asking $35,000,000, $24,250,000 above that median. The middle half of those sales closed between $6,550,000 and $16,000,000. - **Median closed price**: $10,750,000 - **Middle half**: $6,550,000 – $16,000,000 - **Based on**: 29 house sales in Upper East Side - **Period**: September 2021 – July 2026 - **Median $/ft²**: $1,879/ft² Across the 24 of these sales with a published asking price, the median closed at 89% of what it originally asked. 88% of them closed below the original ask. A house is not part of a building of comparable apartments, so this benchmark is drawn from house sales across Upper East Side. Apartment sales are excluded from it entirely. ### How these sales were negotiated - **Sold vs original ask**: 89% of the original ask - **Closed below ask**: 88% of 24 sales - **Listed → in contract**: 164 days (about 23 weeks) - **In contract → closed**: 62 days (about 9 weeks) Across the 24 of these sales with a published asking price, the median closed at 89% of what it originally asked. 88% of them closed below the original ask. Half of these homes were in contract within 164 days (about 23 weeks) of coming to market, based on the 28 with a recorded listing date. Once a deal was agreed, closing took a further 62 days (about 9 weeks), based on the 28 with both dates recorded. 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. Based on 29 house sales in Upper East Side, September 2021 – July 2026. Each figure counts only the sales that recorded the dates it needs, which is why the denominators differ. 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 1013930025. 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.
