A Rare Duplex Residence at 9 East 82nd Street Originally commissioned by Ellen Prentice Kellogg and her son John Harvey Kellogg and designed by architect Henry Andersen, this extraordinary four bedroom, four bath duplex residence is a seamless marriage of historic grandeur and thoughtful modern luxury. Enter through French doors into a breathtaking paneled great room with soaring 12'9" ceilings, a dramatic coffered ceiling, and a magnificent 1920s stained glass window whose multicolored roundels cast a warm jewel-toned glow throughout the space. A European-designed kitchen with marble backsplash, stainless steel appliances and a charming breakfast nook opens directly onto a private terrace, creating a seamless indoor-outdoor flow that is rare and special in the city. The second level is completed by a stunning primary suite featuring a spa-inspired bathroom that must be seen to be believed - floor to ceiling marble, a sculptural freestanding tub, brushed gold fixtures, radiant heated floors, custom lighting, a Toto washlet and an oversized open shower, as well as an additional south-facing bedroom and full bath. Upstairs, wide plank herringbone floors set the tone for the third level, which features two additional bedrooms, two full baths and a sprawling media room. Timeless in character and impeccable in every detail, this is truly a one-of-a-kind Manhattan residence.
