Description
Presenting a magnificent fourteen-into-eleven room simplex maisonette in triple-mint condition, distinguished by extraordinary scale and proportions, and exquisite architectural detail. Located within 998 Fifth Avenue, one of the Upper East Side’s most beautiful and distinguished cooperative buildings, this exceptional residence is one of just seventeen apartments in a landmark building designed by McKim, Mead & White. Expansive and spanning over 5,000 square feet, the apartment has been recently renovated by Julie Hillman, and the pleasing result has been featured in numerous publications. Systems throughout are state-of-the-art. This is a residence of rare sophistication, ideally suited to a discerning buyer with a taste for timeless elegance and refined living. The residence features delightfully sun-flooded interiors, ceilings soaring above 12 feet, two wood-burning fireplaces, and oversized French windows overlooking the fountains and iconic limestone façade of the Metropolitan Museum of Art, as well as the trees lining Fifth Avenue. Uniquely, the residence offers two entrances: one through the building’s majestic interior lobby at 998 Fifth Avenue, and the other its own private entrance directly from Fifth Avenue, with its own distinct address: 999 Fifth Avenue. Entered from the 998 Fifth Avenue lobby, the residence opens to a gracious Foyer leading into a truly dramatic Gallery, which retains its handsome wood paneling, Tennessee marble floors, and carved plaster ceiling. Stretching nearly 33 feet in length, the Gallery sets the tone for the apartment’s extraordinary public rooms. It adjoins an immense Living Room, over 42 feet in length, anchored by a wood-burning fireplace and framed by three large windows facing Fifth Avenue. Opening from the Living Room are two more intimate rooms, also overlooking Fifth Avenue: a sumptuous wood-paneled Library and a sunlight-drenched Den, the latter with its own wood-burning fireplace and en suite bath. Conveniently located off the Gallery are a Powder Room and multiple coat closets. A vast, fully-equipped chef’s eat-in Kitchen has been designed to support both grand entertaining as well as extremely comfortable daily life. There are two separate bedroom wings, both set off from the common rooms. On the southern side of the residence is an enormous Primary Bedroom Suite, with a large corner bedroom awash with southern and western sunlight, two bathrooms, and two large custom-fitted dressing rooms. On the northern side of the apartment are two additional bedrooms, each with its own bathroom, one with very ample closet space. A large laundry room is also located in this wing. Residents of 998 Fifth Avenue enjoy the highest level of service, security, and discretion. This white-glove cooperative, comprised of only 17 residences, offers a recently renovated state-of-the-art fitness center. The apartment also transfers with two sizable private storage rooms, as well as a separate large cold storage bin for wine. An architectural masterpiece, 998 Fifth Avenue was designed between 1910 and 1912 by William Richardson of McKim, Mead & White. At once palatial and understated, the building is crowned by a richly detailed copper cornice and frieze. Most notably, its stately entrance is protected by a remarkable fully glazed ironwork marquee, whose ornate detailing provides a striking contrast to the building’s limestone façade. Long considered a landmark in residential apartment living, 998 Fifth Avenue represents a standard of elegance that has often been aspired to, but rarely achieved.

About Upper East Side
View All Upper East Side ListingsThe Upper East Side remains the gold standard for classic New York elegance. Known for 'Museum Mile' and its low-traffic, tree-lined streets, the neighborhood offers a refined lifestyle away from the midtown bustle.
