There exists but a very limited number of grand duplex maisonette apartments in Fifth Avenue's finest buildings. 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 small 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 facade. 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. Impeccable staffing at this white-glove cooperative include a fully attended lobby, with a full-time doormen, porters, and elevator attendants, and residents benefit from a well-appointed and recently renovated fitness suite. There is a 3% flip tax payable by the purchaser, and financing is not permitted. Pets are welcome.
