PENTHOUSE DUPLEX AT ICONIC 880 FIFTH AVENUE WITH STUNNING SOUTH-FACING TERRACE   A rare offering, this glamorous duplex is the perfect pied-a-terre or full-time residence for the discerning individual seeking gracious living in a distinguished Emery Roth designed Fifth Avenue cooperative.   One of only a handful of duplexes and with ceilings unique to the building of over 10 ft., this residence combines timeless architectural details with the rarity of expansive private outdoor space. The apartment's gracious interiors open onto an approximately 700 square foot south and west-facing terrace with sweeping, open views of the city skyline and partial park views.    A large foyer leads to the main level of the duplex. Perfect for both grand entertaining and gracious living, the generously sized living room with decorative fireplace easily accommodates multiple seating areas and art displays. Filled with light from oversized windows and the open southern exposure, the living room flows into a spacious dining area with room for large gatherings. The windowed kitchen off the dining area offers custom cabinetry, generous storage and an in-unit washer/dryer.  An additional gym or home office space is also located on this floor, along with a Juliette balcony, and additional full bathroom.       A graceful art-deco inspired banister leads to the upper level, and to the spacious bedroom, library/sitting room, and spectacular terrace. Currently configured as a one-bedroom with an open sitting room/library adjacent to the large primary bedroom, the spacious upstairs floor plan offers versatility and the flexibility to use the space to fit one's own needs.  The bedroom and sitting room open directly onto the spectacular approx. 700 sq-ft. terrace. Framing panoramic open city views to the south and partial views of Central Park to the west, this urban oasis is perfect for al-fresco dining, cocktail receptions, relaxing and lush plantings.    The large primary bedroom suite features abundant closet space, and a spa-like bath with soaking tub and rain shower. The library/sitting room, with pocket doors opened or closed to the primary bedroom for privacy, also enjoys floor-to-ceiling windows and direct access to the terrace. Walk-in closets and a wall of closets on the upper landing provide abundant storage.     Rarely does a home combine such architectural distinction, private outdoor space, and a premier Fifth Avenue address, directly across from Central Park.  Completed in 1948, 880 Fifth Avenue is an exceptional full-service cooperative designed by famed architect Emery Roth and ideally located across from Central Park.
