Extensively remodeled, this "art-studio" duplex apartment has a grand double-height living room (17') with a working fireplace, and on the 1st floor, a gourmet kitchen, large dining room, artists' work room (or office), and a powder room. On the upper level are a master bedroom suite, with a huge walk-in closet and bath, a guest suite with bath, a second entrance directly to the elevator landing, plentiful storage closets, and a built-in office area overlooking the studio. The building's desirable 1903 elements have been preserved, the intimate lobby, the huge cast-iron elevator and electrified gas fixtures on the landing. In the apartment these include a huge double-height window looking north over the Upper West Side, a generous mezzanine balcony overlooking the double-height space, west facing windows in the dining room and master bedroom (an unusual feature on West 67th Street), and the fireplace. And so much more has been added, a beautiful kitchen for a serious cook with a Wolf cook-top, and refrigerator and freezer drawers, Fisher Paykel dishwasher drawers, Bofi cabinetry and a large center island, central air-conditioning, a five fixture master bath, with tub, shower and two sinks, approx. 47' of built-in cabinets in the living room and dining room, a long wall of bookcases, a library ladder . . .and much more. The architect, Armand Le Gardeur, was chosen for his refined eye and ability to resolve the most exacting detail. The owners, a textile designer and a builder who who has worked at the highest levels, brought extensive background to the design and executed the renovation with their own crew.
