Designed by legendary architect J. E. R. Carpenter, this intimate white-glove cooperative contains just thirteen grand residences and a single maisonette - a uniquely elegant and generously sized 2-bedroom home with 3 large bathrooms, moments from Central Park. Positioned on the corner of East 66th Street and Park Avenue, this sophisticated maisonette combines classic prewar architecture with thoughtful modern upgrades. High ceilings, original moldings, herringbone floors, and beautifully scaled rooms create a sense of understated grandeur throughout. The expansive living room enjoys natural light from Park Avenue and offers an exceptional setting for entertaining or quiet daily living. The kitchen has recently been updated with premium appliances, including a Bosch refrigerator, dishwasher, and oven, along with an in-unit Miele washer and dryer - seamlessly integrates contemporary convenience into the home's timeless character. Privately situated away from the entertaining spaces, the two bedrooms offer exceptional tranquility and generous proportions. A separate space can easily act as a home office or open dining room. Abundant closets and deeded private storage further enhance the home's livability. Residents of 635 Park Avenue enjoy an exceptionally discreet and attentive level of service, including a full-time doorman, porter, resident superintendent, fitness room, and private storage. Just moments from Madison Avenue boutiques, world-class dining, the museums, the Park Avenue Armory, and Central Park, this is Upper East Side living at its most refined. ## Property Details - **Property Type**: Co-op - **Beds**: 2 - **Baths**: 3 - **Rooms**: 5 - **Stories**: 13 - **Year Built**: 1913 - **Common Charges**: $6,637 / Monthly - **Listed On**: May 14, 2026 - **Days on Market**: 121 Days ### Residence Features - High Ceilings - Dishwasher ## Sales Evidence ### Recent closed sales 3 apartments at 635 PARK Avenue have recorded sales since September 2021, the most recent for $8,250,000 in February 2025. Prices are the figures recorded with the City, not asking prices. | Unit | Beds | Sold Price | Sold | Source | | --- | --- | --- | --- | --- | | 9th Floor (Apartment) | 4 | $8,250,000 | February 27, 2025 | MLS | | 8THFL (Apartment) | 5 | $6,750,000 | October 21, 2024 | MLS | | 2nd Floor (Apartment) | 3 | $9,700,000 | August 4, 2022 | MLS | Every row is a recorded transaction, including ancillary spaces such as storage and staff rooms where they were sold separately. Those are excluded from the benchmark below. ### How this price compares The median closed price for comparable co-op two-bedroom sales in Lenox Hill is $1,397,500, based on 320 sales between September 2024 and July 2026. This home is asking $1,850,000, $452,500 above that median. The middle half of those sales closed between $1,047,500 and $1,800,000. - **Median closed price**: $1,397,500 - **Middle half**: $1,047,500 – $1,800,000 - **Based on**: 320 co-op two-bedroom sales in Lenox Hill - **Period**: September 2024 – July 2026 Square footage is recorded for only 96 of these 320 sales (30%), so no price per square foot is shown for this group. Co-op sales rarely carry a floor area, and a figure drawn from a handful of them would not describe the rest. Across the 301 of these sales with a published asking price, the median closed at 96.2% of what it originally asked. 66% of them closed below the original ask. This building has not had enough comparable sales of its own in the period to support a median, so the benchmark is drawn from Lenox Hill instead. ### How these sales were negotiated - **Sold vs original ask**: 96.2% of the original ask - **Closed below ask**: 66% of 301 sales - **Listed → in contract**: 81 days (about 12 weeks) - **In contract → closed**: 92 days (about 13 weeks) Across the 301 of these sales with a published asking price, the median closed at 96.2% of what it originally asked. 66% of them closed below the original ask. Half of these homes were in contract within 81 days (about 12 weeks) of coming to market, based on the 300 with a recorded listing date. Once a deal was agreed, closing took a further 92 days (about 13 weeks), based on the 304 with both dates recorded. A co-op board package and its interview account for much of that. 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 320 co-op two-bedroom sales in Lenox Hill, September 2024 – July 2026. Each figure counts only the sales that recorded the dates it needs, which is why the denominators differ. ### Price trend Median sold price for co-op two-bedroom sales in Lenox Hill, 2016 to 2026. The series is held to one bedroom count and one ownership type for the same reason: an unfiltered median tracks which apartments sold, not what they were worth. | Year | Median sold price | Sales | | --- | --- | --- | | 2016 | $1,400,000 | 36 | | 2017 | $1,440,000 | 135 | | 2018 | $1,427,500 | 126 | | 2019 | $1,400,000 | 105 | | 2020 | $1,302,500 | 76 | | 2021 | $1,300,000 | 245 | | 2022 | $1,350,000 | 207 | | 2023 | $1,390,000 | 151 | | 2024 | $1,350,000 | 163 | | 2025 | $1,400,000 | 180 | | 2026 | $1,475,000 | 81 | This building does not have enough sales with a recorded floor area to chart its own price per square foot, which is usual for a co-op. The series above follows comparable homes across Lenox Hill instead. 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.
