Three setback terraces wrap the apartment, creating a rare sense of openness, light and privacy in the heart of the Upper East Side. Completely reimagined in an extensive renovation by architect Stephen Morgan and acclaimed designer Marshall Watson, the residence pairs the elegance of its prewar architecture with a sophisticated contemporary sensibility. Raised ceilings, widened doorways, central air, new windows, and updated plumbing and electrical systems were integrated into interiors that draw gracefully from traditional, modern and Art Deco influences. Throughout, exceptional materials and bespoke details-including brass and malachite hardware and distinctive modern lighting-give the home a character that feels both refined and highly individual. A gracious entry gallery opens to a sun-filled corner living room of impressive scale, where oversized windows and French doors lead directly to the wraparound setback terraces. The result is an unusually seamless connection between the interior rooms and the apartment's extraordinary outdoor spaces. The beautifully appointed primary suite enjoys direct access to two of the three terraces and features a luxurious en-suite bath with a walk-in shower. A second bedroom suite, cleverly concealed behind a secret bookcase, has its own en-suite bath as well as direct terrace access. The formal dining room, equally inviting as a den, is anchored by a spectacular custom bar designed and fabricated by Amuneal. Textured bronze and brass cabinetry, rich millwork and dramatic suspended glass shelving create a jewel-like centerpiece for entertaining. The bar is exceptionally equipped with True Residential refrigeration, including three wine coolers, a beverage center and a clear ice maker. The windowed kitchen is both beautiful and highly functional, with bleached-walnut cabinetry, exquisite hardware, an Italian range beneath a custom brass hood, a 36-inch True Residential upright refrigerator and two dishwashers. Milk-white Calacatta Gold marble tops the counters throughout. A third bedroom, a generously proportioned full bath and shower, plus a dedicated laundry area complete the residence. Built in 1930 by renowned architect Emery Roth, 784 Park Avenue is one of Park Avenue's distinguished prewar cooperative buildings. Residents enjoy a 24-hour staffed lobby, fitness room, finished courtyard, bicycle room, laundry facilities and storage. Ideally situated just two blocks from Central Park, the building is surrounded by the Upper East Side's exceptional restaurants, boutiques, cultural institutions and convenient transportation. Rarely does a Park Avenue residence offer this combination of architectural pedigree, sophisticated design, three private terraces and beautifully considered entertaining spaces-a home that is as distinctive as it is livable. ## Property Details - **Property Type**: Co-op - **Beds**: 3 - **Baths**: 3 - **Rooms**: 7 - **Stories**: 19 - **Year Built**: 1929 - **Common Charges**: $7,243 / Monthly - **Listed On**: Sep 15, 2026 - **Days on Market**: 1 Days ### Residence Features - Building Other - Washer Hookup - In Unit - Washer Dryer Allowed - City - Panoramic ## Estimated Monthly Payment **$66,657 / month**, assuming a 20% down payment ($2,350,000), a 6.5% interest rate and a 30-year term.

Those are excluded from the benchmark below. ### How this price compares - **This home**: $11,750,000 - **Median sold price**: $4,400,000 - **Difference**: +$7,350,000 (+167%) - **Comparable sales**: 5 - **Sales from**: September 2021 – April 2025 - **Middle half of those sales**: $3,500,000 – $4,950,000 Based on three-bedroom sales at 784 PARK Avenue. Square footage is recorded for only 2 of these 5 sales (40%), 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. ### How these sales were negotiated - **Sale-to-list price**: 90.7% (5 sales) - **Sold below asking**: 80% (5 sales) - **Typical time to find a buyer**: 203 days (3 sales) - **Typical time to close**: 145 days (3 sales) Based on three-bedroom sales at 784 PARK Avenue with the required listing and closing data. 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. ### Price trend Median sale price, co-op three-bedroom sales in Lenox Hill | Year | Median sold price | Sales | | --- | --- | --- | | 2016 | $2,397,500 | 12 | | 2017 | $2,500,000 | 59 | | 2018 | $2,572,500 | 54 | | 2019 | $2,282,119 | 80 | | 2020 | $2,167,500 | 38 | | 2021 | $2,202,500 | 96 | | 2022 | $2,475,000 | 108 | | 2023 | $2,250,000 | 90 | | 2024 | $2,460,000 | 72 | | 2025 | $2,550,000 | 90 | | 2026 YTD | $2,673,000 | 55 | Based on recorded co-op three-bedroom sales in Lenox Hill. 2026 is year-to-date. Sales data through December 2025. 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.
