This glorious and glamorous maisonette is such a rarity. Located at 834 Fifth Avenue, among the Upper East Side’s most coveted addresses, and designed by master architect, Rosario Candela, this residence is truly splendid. Blessed with pleasing scale, soaring high ceilings, elegant proportions, and delightfully sun-flooded interiors, this duplex offers the discretion and privacy of a fine townhouse as well as the security and service provided by a building of this caliber. Notably in this divine apartment, every major room of this duplex faces onto Fifth Avenue and offers delightful treeline outlooks of Central Park. The apartment features two entrances, one from each floor of the building’s interior, the other its own private entrance (and address) on Fifth Avenue. A separate service entrance through the building ensures that deliveries are discreetly managed and escorted by the building’s back-of-house staff. From its private Fifth Avenue entrance, the classic and very grand Gallery has an attractive stone floor and is anchored by a gracefully curving staircase. Coat closets and a powder room are conveniently accessible. The Gallery opens to two entertainment rooms, both overlooking Fifth Avenue: a sumptuous, wood-paneled Library with a woodburning fireplace, and an elegant Dining Room. Beyond, a large eat-in Kitchen, designed for the consummate chef, is perfect for extremely comfortable daily life but also scaled to accommodate a large catering crew and chef when for grand entertaining. Above, the second floor presents a magnificently-scaled step-down Living Room with a wood burning fireplace and marvelous oversized windows looking onto Central Park. On this level, there are also three large Bedrooms, two of which stretch along Fifth Avenue with leafy outlooks. Each has an ensuite bath and a copious dressing closet. A third very generously-scaled Bedroom is nearby and also has an ensuite bath and ample closets. Beyond, there are three staff bedrooms- two of which could easily be combined to create a large fourth Bedroom. A large storage bin, a private basement laundry room, and a wine vault are also included. Designed by the esteemed Rosario Candela in 1931, 834 Fifth Avenue is notable for its restrained and elegant neoclassical limestone façade. Representing the highest standard in refined and luxury living, this stately building was constructed to include a preponderance of duplexes along with a penthouse triplex and three duplex maisonettes.

Prices are the figures recorded with the City, not asking prices. | Unit | Beds | Sq Ft | Sold Price | $/ft² | Sold | Source | | --- | --- | --- | --- | --- | --- | --- | | MAIS/A (Duplex) | 3 | 5,000 | $14,750,000 | $2,950/ft² | March 24, 2025 | City record · MLS | | 1/2B (Apartment) | — | — | $7,000,000 | — | October 7, 2024 | City record | | 7B (Apartment) | — | — | $21,000,000 | — | November 10, 2022 | City record | 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 - **This home**: $14,995,000 - **Median sold price**: $13,750,000 - **Difference**: +$1,245,000 (+9.1%) - **Comparable sales**: 4 - **Sales from**: September 2024 – March 2026 - **Middle half of those sales**: $10,631,250 – $15,000,000 Based on co-op six-bedroom sales in Lenox Hill. Square footage is recorded for only 2 of these 4 sales (50%), 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. 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 - **Sale-to-list price**: 90% (3 sales) - **Sold below asking**: 100% (3 sales) - **Typical time to find a buyer**: 620 days (3 sales) - **Typical time to close**: 118 days (3 sales) Based on co-op six-bedroom sales in Lenox Hill 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. Sales data through March 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.
