Description
Ideally positioned at the corner of Fifth Avenue and East 80th Street, this splendid duplex residence occupies the entire fourth and fifth floors of 990 Fifth Avenue, an elegantly discreet boutique prewar cooperative. Spanning nearly 4,500 square feet, the apartment is blessed with sweeping views of the treetops of Central Park that extend to the iconic Billionaires’ Row skyline and to the magnificent limestone facade of the Metropolitan Museum of Art. Located within one of Rosario Candela and Warren & Wetmore’s very elegantly drawn buildings, this apartment is also remarkable for its exceptionally gracious scale and proportions, Glamorous and sophisticated, the apartment presents an ideal blueprint for a balance between grand entertaining and comfortable private living. Benefitting from southern, eastern, and western exposures, the apartment is drenched in sunlight throughout the day. Throughout the plan, beautifully proportioned entertainment rooms and four spacious bedrooms are enhanced by ceilings nearly 11 feet in height on the lower level, four wood-burning fireplaces, and exquisite architectural detailing. A private elevator landing opens to an entrance gallery anchored by a sweeping marble staircase, from which the three entertainment rooms emanate. The magnificent corner living room, measuring approximately 24 by 25 feet, is framed by single pane windows that capture the breathtaking views and perennial sunlight. Rich wood detailing, parquet floors, and a wood burning fireplace with a marble surround lend warmth and grandeur to this exceptional entertaining space. Just adjacent, the more intimately-scaled library features handsome wood paneling and a wood-burning fireplace. Nearby, the impressive formal dining room, also with a wood-burning fireplace, extends to more than 22 feet in length and features attractive decorative moldings. Beyond, a spacious, windowed eat-in kitchen offers a center island and abundant custom cabinetry and is supported by an adjoining pantry, laundry area, and a staff room with a full bath. A powder room and coat closets complete this level. The serene upper level is devoted to private living, with four generously proportioned bedrooms and a separate office, den, or media room, as well as very ample closets throughout. Occupying the coveted corner position, with views south and west, the expansive primary suite enjoys spectacular views over Central Park and features the residence’s fourth wood-burning fireplace, custom built-ins, two walk-in closets, and an ensuite bathroom with a separate soaking tub and shower. Three additional bedrooms each offer ensuite bathrooms, bright southern exposures, and ample closets. Elevator access and separate service entrances on both floors further enhance the convenience and functionality of this thoughtfully arranged residence. Designed in 1926 by Rosario Candela and Warren & Wetmore, 990 Fifth Avenue is a boutique white-glove cooperative comprised of just six residences. Beyond its limestone façade; the residences convey the sublimely understated grandeur, remarkable functionality, and enduring elegance typical of these revered architects. Accessed by a discreet canopied entrance on East 80th, the building is known for its unparalleled security. Residents benefit from deeded private storage and the use of a newly constructed gym. No financing is permitted, and there is a 1% flip tax. 990 Fifth Avenue has no summer work rules, and pets are welcomed.

Broker Commission Disclosure: Broker commissions are not set by law and are fully negotiable.
How working with a buyer's agent works: I work for you, not the seller. Before I show you anything, New York brokerage rules ask us to put that in writing: an agreement and a disclosure that say I work for you and negotiate on your behalf. The agreement is non-exclusive: you can work with other agents, it runs for a short fixed term we agree on, and you can end it with a note. You may attend open houses independently without an agreement. Read how it works
