Grand Park Avenue duplex renovated to the highest level is available in one of the Upper East Side's most prominent addresses - 730 Park Avenue, a white-glove, full-service cooperative with a discreet entrance on East 71st Street. Residence 10/11C is an architectural masterpiece having undergone a multi-year renovation to combine two units into a seamless duplex with six bedrooms plus a staff suite, eight full bathrooms and three powder rooms.

Upon arriving to the 10th floor, the glass-enclosed entry vestibule clad in palissandro bluette marble is the first glimpse of the home's subtle yet luxurious design that is incorporated all throughout. Through the private elevator entry foyer is the blue limestone cantilevering staircase that is not only visually show stopping but also functions as the main connection between the two floors. The corner great room is ideal for formal entertaining with its generous proportions, wood-burning fireplace, gorgeous powder room and wet bar connecting to the home's library. The library, clad in cerused white oak, features an additional wood-burning fireplace.

Adjacent to the great room is the formal dining room fitted with a custom banquette and stained white oak paneling. The windowed kitchen, designed by Arclinea, features stainless steel cabinetry and countertops and a suite of integrated appliances including double dishwashers, six-burner range, wine fridge and side-by-side refrigerator and freezer. The kitchen has no shortage of additional storage with floor-to-ceiling glass cabinetry, butler's pantry and a separate office that can act as a second staff room. The remainder of the 10th floor is dedicated to the incomparable primary suite that allows for the ultimate level of privacy. The suite features a corner primary bedroom, sitting room, two windowed marble bathrooms and dual custom-fitted dressing rooms.
