New listing being shown now, by appointment.  This prewar cooperative apartment stands out for the grand scale of its rooms and fine  architectural detailing and finishes. Under the direction of the distinguished Albert Hadley, this classic 14-room simplex has been renovated and restored to a chic and sophisticated 12-room Manhattan residence.  A private elevator landing and 29-foot gallery lead to the public rooms: a 32-foot paneled corner living room, formal dining room, elegant library and powder room.   An outstanding feature of the apartment is the newly-completed custom cook's kitchen with a spacious breakfast room adjacent. The fitted custom cabinets and soapstone counters were designed and created by the designer Carlos Aparicio, with every detail carefully considered. From the Sub-Zero refrigerators and freezers to the enormous Wolf range, the premium appliances have been carefully handpicked. Sliding glass doors separate the preparation area from the spacious breakfast room, and create the opportunity to cook with or without an audience. Directly adjacent are two staff rooms and a full private bath.   The private living quarters consist of five generously proportioned bedrooms with baths en-suite. The master bedroom has its own fireplace, as do the living room, library, and dining room. Light streams in through the substantial western exposures on Park Avenue and south to East 72nd Street.  765/775 Park Avenue is listed among the  grandest of the grand  by the noted New York Times architecture writer Christopher Gray. Designed by the renowned architect Rosario Candela in 1927, his  elevated concepts of layout, amenities, spaciousness and luxury  still set the standard in New York City homes.   Co-exclusive. 3% flip tax.
