Description

Open and airy, this full floor apartment offers dazzling views of Central Park and the iconic New York City skyline, including the Empire State Building to the south and pretty, northern views over classic townhouses. Impeccably renovated by award winning Gabellini Sheppard Associates, the 9th floor at 21 E. 79th Street is an elegant, carefully crafted backdrop for both modern and traditional furniture and art. The floor plan has been brilliantly conceived and allows the residence to feel loft-like while pocket doors create divided rooms and more formal spaces when desired. In addition to a wonderful layout, the 9th floor features the privacy of a full floor residence, dramatic ceiling heights, dual exposures from a corner living room and three wood burning fireplaces. A spacious and private south facing primary suite with custom built dressing room/office includes a spa-like bathroom with two sinks, a separate Zuma bathtub and large marble shower. An impressive Bulthaup chef's kitchen offers tasteful soapstone countertops, a Gaggenau stove, two Miele dishwashers, two sinks, a Subzero refrigerator, supplementary below-counter refrigerator drawers and a wine fridge. The apartment also includes an inviting sunny library, a large dining room, a wing with three additional bedrooms for guests or family and a charming laundry room with a view. Floors throughout the home are comprised of 7-inch select grade wide-plank oak, closets are custom finished and the walls boast an art hanging system by Arakawa. The heating and air conditioning system as well as electric shades and a/v are controlled by a Savant system. 21 East 79th Street is a highly regarded, pre-war cooperative located between Fifth and Madison Avenues. Situated in the most prime Upper East Side location on storied 79th Street among limestone mansions and near the best Museums, galleries, restaurants and shopping the city has to offer, the co-op consists mostly of full floor residences and prides itself on security and service.

The Upper East Side remains the gold standard for classic New York elegance. Known for 'Museum Mile' and its quiet, tree-lined streets, the neighborhood offers a refined lifestyle away from the midtown bustle. While famous for its historic cooperatives, the area has seen a recent surge in ultra-luxury new construction condos, particularly along the Second Avenue Subway corridor, making it a top choice for both traditionalists and modern buyers.
