Property Details
Description
This large, magnificently proportioned, 14-into-10 room apartment encompasses the entire 9th floor of 635 Park Avenue, a building designed in 1912 by the renowned architect J.E.R. Carpenter. Attractively renovated by Colefax and Fowler and other designers, the apartment has been meticulously maintained and, truly, is in pristine condition. The property is full of light with 10’ ceilings and has large eight-over-eight mullioned windows as well as central and thru-wall air conditioning throughout. One enters the apartment from a private elevator landing leading into a foyer and the memorable circular entrance gallery. This delightful and unusual space serves as the hub of the apartment and the living room, library, and stunning Biedermeier style wet bar all radiate out from it. The elegant corner living room, facing Park Avenue, is of exceptionally large size with woodburning fireplace and flows into the equally impressive sun-filled formal dining room that comfortably seats 18 people. The intimate library, with woodburning fireplace, is fitted with bookshelves. A long corridor, off the foyer, leads to the three large bedrooms with en suite baths. The primary one, entered through a discrete elliptical vestibule with two closets, is located on the corner of 66th Street and Park Avenue. It has fabulous views looking north up Park Avenue and west towards Central Park. Its spacious over-size bathroom has a walk-in shower, two sinks and an open-plan dressing room with two large closets. At the other end of the bedroom hall is a fourth, smaller bedroom, currently used as a gym. The newly renovated, bright and airy kitchen, beautifully designed by Bilotta Kitchens with top of the line appliances and cabinets, has a large central island and access to the dining room and wet bar. Also, off the kitchen, are the comfortable and appealing media room with its flat screen TV and the generous laundry room with great storage space and direct access to the service elevator. There are two powder rooms in the apartment: one off the entrance foyer, the other beside the fourth bedroom or gym. 635 Park Avenue, conveniently located on the corner of 66th Street across the street from the Park Avenue Armory, is a full-service cooperative with live-in super and full-time doormen. The building has a fitness room and private storage space in the basement. 50% financing allowed. 1.5% flip tax
