Description

635 Park Masterpiece- 11th Floor For the first time in decades a high floor sun flooded 14 room grand residence spanning the entire 11th floor with views from all 4 exposures has come to market for sale at 635 Park Avenue. Considered by many as one of New York's very best Prewar buildings and listed as 'The Top 10 Great City Apartment Buildings' by The New York Times writer Paul Goldberger who also described that 'J. E. R. Carpenter produced one of the best floor plans in Manhattan at 635 Park Avenue'. With it's own private elevator landing, this immensely gracious full floor apartment is filled with sunlight and views that span across the home. An elegant gallery leads to an impressive suite of old world grand rooms, each with stunning wood burning fireplaces, impressive high ceilings, prewar details and master carpentry. They include a palatial corner living room with extraordinary crafted wood paneling. This room opens to an enormous private dining room through wide sliding pocket doors which when left open creates the most beautiful and elegant floor through with views from one end of the home to the other. The oversized pane windows flooding the space with sun and views are simply remarkable. The custom book shelved library complete this grand area of entertaining spaces. The bedroom wing includes a spacious corner Park Avenue facing master bedroom suite. Additionally there are 4 spacious and sun flooded bedrooms with en suite baths and an abundance of oversized closets. All bedrooms clear neighboring buildings and have wonderful open views from their stunning pane windows. Completing the gracious layout, there is a vast eat-in Kitchen with an East facing breakfast room, perfect for morning light and informal dining and lounging. Off the kitchen is a laundry area and pantry, service entrance as well as the fifth bedroom which may be used as a staff room or additional office. This home also has a central HVAC system. Constructed in 1912 and featuring thirteen full floor residences, 635 Park Avenue was designed by renowned architect J.E.R. Carpenter and is located on the Southeast corner at 66th Street. The building has a finely detailed, light-brown brick facade in Italian-Renaissance-palazzo style. This full service, white glove cooperative features a full time doorman, an elevator operator, a live-in superintendent and storage.

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.
