A Grand Duplex Designed for Sophisticated Living and Entertaining. Perfectly positioned on one of the most coveted stretches of Park Avenue, this exquisite six-bedroom, four-and-a-half-bathroom duplex is the epitome of timeless elegance, modern refinement, and gracious entertaining. Located in a white-glove prewar cooperative, this residence offers voluminous proportions, impeccable design, and a level of detail rarely seen in today's market. A semi-private elevator landing opens into a gracious entrance gallery, introducing the home's elegant scale and classic architectural detail. From here, the eye is drawn into the expansive corner living room, bathed in natural light from the oversized windows with sweeping Park Avenue exposures. Anchored by a gas-burning fireplace, this refined space is ideal for both intimate gatherings and grand receptions. Flowing seamlessly from the living room is a stunning formal dining room-a true showpiece for any host-complete with a custom wet bar, wine cooler, and a marble-clad powder room that reflects the home's attention to luxury and comfort. The eat-in kitchen, masterfully designed by Clive Christian, is a chef's dream, featuring handcrafted cabinetry, marble countertops, a center island, top-of-the-line appliances, clever storage solutions, and a sunlit breakfast bar for everyday dining. The main level also features three proportioned bedrooms, each with generous closet space, and two marble bathrooms. One bedroom is currently used as a library and another bedroom is currently used as a home office. In addition the bath fixtures and the sinks are all equipped with Cheryl Wagner fixtures (well known for their elegance). Upstairs, three additional bedrooms await, including a grand primary suite facing east with serene morning light, abundant closets, and a sophisticated en-suite marble bath. Throughout the residence, rich hardwood floors, lofty ceilings, and custom millwork elevate every inch of the grand residence. Exceptional closet and storage space is thoughtfully integrated across both levels. The residence also comes with its own large storage unit (in the lower level of 875 Park Ave). 875 Park Avenue is a historic and architecturally distinguished building, designed in 1912 and so esteemed that its original developer, William Korn, chose it as his personal residence. This white-glove cooperative offers 24-hour doorman and concierge service, private storage, a state-of-the-art fitness center, and pet-friendly policies. Located just moments from Central Park, Museum Mile (including the Metropolitan Museum of Art and the Guggenheim), and iconic establishments such as The Carlyle Hotel, this residence offers unparalleled access to the very best of the Upper East Side. 875 Park Avenue allows 50% financing, and the 2% flip tax is payable by the seller.
