Description

First A-Line 4-5 bedroom duplex to come on the market in over a decade.

"One of the city's most distinctive and elegant residential buildings, this very handsome apartment building on the northeast corner at 85th Street was erected in 1929 as a cooperative. The 15-story building has 27 apartments and was designed by Rosario Candela and Kenneth M. Murchison and erected by John and Joseph Campagna, the son of Anthony Campagna, one of the city's most important developers of luxury residential buildings. Candela was the leading architect of luxury apartment buildings of his era."

This building has a 24 hour doorman and full staff including a live-in resident manager. The building is pet friendly, ALLOWS 50% FINANCING AND NO SUMMER WORK RULES and there is storage in the basement.

This exclusive 13 into 12 room duplex has retained the Candela original details, but has been renovated and updated for today's living. The apartment feels like a townhouse with the private elevator vestibule opening to an elegant center gallery with stenciled floors and a stunning curved staircase. All major rooms are positioned off the center gallery and are perfectly proportioned with high ceilings and large windows. The sun filled corner living room has both southern and Park Avenue tree-lined exposures, oversized windows and a wood-burning fireplace. A highly important and unusual feature of this apartment is the picturesque views of beautiful architecture and Park Avenue from every major room.

Double doors lead to the adjacent library, which features a wood burning fireplace, exquisite paneled walls, bookcases and views of Park Avenue. An impressive 20' x 17' south facing dining room is perfectly proportioned for grand entertaining. The tree-line views make this a truly magnificent room.

The cook's kitchen, large windowed pantry, and breakfast room also share the same south facing tree-lined views as the dining room. A laundry room, staff room and bath complete the first floor.

A Candela signature powder room is situated mid-staircase. The second floor bedroom hallway, like the gallery, opens to five perimeter rooms. The southwest corner facing master bedroom is gracious, sun filled, and has a third working wood-burning fireplace which is only found in a couple of A-line apartments in the building. There are three additional bedrooms all with great scale, light, and views. There is also an enormous walk-in closet and a home office. The sixth bath is now a spa-quality sauna. These rooms can easily be repurposed as a fifth bedroom with a bath. This apartment is a must see for anyone looking for large space, scale, and four-five bedrooms.

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.
