Sensational 12 Room Carnegie Hill Duplex - This incredible home is a one of kind combination of two C-Line apartments at 1165 Fifth Avenue, featuring a sprawling layout of grand scale rooms, 9 foot plus ceilings, wide-open eastern exposures, and southern peeks of Central Park and the reservoir. The renovation required a complete transformation of the layout, and the result is a beautifully conceived apartment that includes five bedrooms, five full bathrooms, and multiple formal and casual living spaces. Upon entry from the 15th floor, a gracious entry foyer leads to a large traditional living room with wood-burning fireplace and herringbone floors, that connects to a long and wide formal dining room that's ideal for entertaining. The gourmet kitchen is enormous, with a center island, crisp white cabinetry, high-end stainless-steel appliances, two windows with views of Central Park and a separate breakfast room. On the opposite side of this floor there is a large corner primary bedroom with marble ensuite bath, plentiful closets, and a stunning corner library with second full bath completes the 15th floor. The custom-built staircase off the kitchen leads to the 14th floor, which includes three additional bedrooms, three full baths and two versatile living spaces: a spacious media/game room that could easily be converted into a home gym or a billiards room, and a fabulous family room has a second wood-burning fireplace. All of the bedrooms are well proportioned, with tremendous closet space, and each have magnificent eastern views. A dedicated laundry room and staff room/home office with a full bath complete the 14th floor. The entire apartment has central air-conditioning, upgraded electric, and every window has been replaced. 1165 Fifth Avenue is a premier Carnegie Hill co-op with 24-hour doormen and resident manager, a beautiful lobby, bike room, central laundry, health club, and storage transfers with the apartment.
