Description

Gracing the sunlit corner of Fifth Avenue and 86th Street, directly across from Central Park and the iconic Jacqueline Onassis Reservoir, this exceptional residence at 1050 Fifth Avenue epitomizes classic Fifth Avenue living. Bathed in natural light from oversized windows on three exposures, this approximately 1,700-square-foot home offers a unique combination of a center hall layout with grandly scaled rooms, modern elegance, timeless architectural integrity, and serene views. This five-room home has been meticulously designed by an accomplished architect to balance sophistication with a sense of ease. Oversized windows frame luminous exposures from morning to dusk, filling each room with warmth and airiness. A formal entrance foyer opens into a gracious gallery that sets the tone for the home’s relaxed sophistication. The gallery unfolds into an impressive enfilade of entertaining rooms—nearly 60 feet in length—comprising an expansive living room and an elegant dining room. Sunlight floods the home throughout the day, while handsome, custom millwork and hardwood floors enhance the living and dining spaces. Beautifully appointed built-ins and a decorative fireplace anchor the living room with tailored sophistication and exceptional functionality, while generous wall space throughout provides an ideal setting for art collectors. From the tree-lined vista of East 86th Street, the living room and primary suite enjoy enchanting views of the verdant canopy of Central Park and the stately architecture of the Neue Galerie beneath an open sky. The dining room, bathed in soft northern light, overlooks a peaceful interior courtyard and terrace. The windowed galley kitchen, outfitted with stainless steel appliances and an in-unit washer/dryer, provides ample space for culinary pursuits or catered affairs. For those desiring a more open concept, the kitchen may be seamlessly combined with the dining room, which also functions beautifully as a third bedroom or library. The private quarters are equally well-appointed. The luxurious primary suite includes an ensuite bath, two walk-in closets, and an additional closet. The spacious second bedroom—currently used as a study and den—features elegant built-ins, a walk-in closet, and access to a well-appointed second bath. Throughout, the apartment offers exceptional storage, two large coat closets in the foyer, and thru-wall air conditioning in every room. Built in 1959 by Lipman and Spitzer, 1050 Fifth Avenue remains one of the area’s most distinguished full-service cooperatives, offering a 24-hour doorman and concierge, attended elevators, a live-in resident manager, and an array of sought-after amenities: a fitness center, bike room, storage units (subject to availability), laundry room, on-site garage with a reduced monthly rate, and a panoramic roof terrace with sweeping views of Central Park and the Manhattan skyline. 1050 Fifth Avenue permits pets with board approval, 50% financing, guarantors, co-purchasing, and secondary residences on a case-by-case basis. Smoking, subletting, diplomat purchases, or purchases by parents for children are not allowed. There is a 1% flip tax. Ideally situated just moments from the Metropolitan Museum of Art, the Guggenheim, Madison Avenue’s world-class boutiques, and the city’s finest dining and cultural institutions, this remarkable home offers an exceptional opportunity to experience Fifth Avenue elegance at its most inviting.

The 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. 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.
