Wonderful opportunity to purchase a rare duplex Fifth Avenue maisonette facing Central Park, with entrances off the lobby and the avenue as well as staffed elevator service. Estate of the late architect Henry Cobb, partner to I.M. Pei and renowned designer of some of the world's most notable buildings, including Boston's John Hancock Tower. This lovely apartment was cleverly designed by Cobb so that many of the living spaces face treelined 78th street and the handsome limestone facade of the Duke mansion through a long line of windows. On the second floor, the primary bedroom and adjacent library (with wood burning fireplace) enjoy verdant views of Central Park. This suite also has a large windowed bathroom and gracious dressing room with multiple closets. The generous, gourmet eat-in kitchen has a restaurant grade cooktop, two Gaggenau ovens, and a Traulsen refrigerator. Behind this are a full bath, massive laundry room with pantry storage, and a small bedroom with two sunny exposures. The first floor offers multiple uses for a purchaser. The two main rooms were used as an office and a sculpture studio (with wood burning fireplace), and there is an adjoining full bath. These spaces could easily serve as a guest suite, playroom, home office with waiting room, the choices are endless. The apartment's multiple access points add convenience and expand the options for use. Steps from the Metropolitan Museum, this is truly one of the most special and delightful apartments on the market. Financing permitted on a case-by-case basis.
