Penthouse D at 200 West 88th Street is a remarkable five-bedroom, five-and-a-half-bathroom full-floor residence by Robert A.M. Stern Architects. Spanning 4,364 interior square feet and 959 square feet of private outdoor space, it commands 360-degree exposures, soaring ceilings up to 11'2" and three distinct outdoor settings, including a signature arched loggia facing Central Park. A dedicated elevator corridor and private arrival with valet closet establish a sense of privacy. Beyond the foyer, a grand formal living room unfolds beneath signature arched windows, anchored by a custom fireplace with a Blue de Savoie Light marble mantel. French doors open to the 34-foot arched loggia. The formal dining room accommodates twelve to fourteen guests and opens to a second loggia, creating a dramatic sequence of indoor and outdoor entertaining spaces. Three-inch white oak herringbone floors distinguish the entertaining rooms; bordered four-inch oak planks line the bedrooms and galleries. Designed by Christopher Peacock with RAMSA, the windowed eat-in kitchen features honed Olympian White Danby marble countertops and backsplash, quarter-sawn oak cabinetry painted in Porcelain White, an oversized island and corner banquette. Fitted drawers, pantry storage, nickel-detailed vented hood and hand-brushed hardware reflect meticulous craftsmanship. Appliances include a Sub-Zero refrigerator/freezer, separate freezer and wine refrigerator, a 48-inch Wolf induction range, wall oven, speed oven and warming drawer, and two Miele dishwashers. RAMSA by Kallista Kitchen Fittings make their debut here; pocket doors offer separation from formal spaces. The exceptionally private primary suite opens through two sets of French doors onto a 35-foot terrace. A morning kitchen and two WICs, including a corner windowed dressing room, complete the retreat. Its windowed five-fixture bathroom pairs Precious White marble, radiant-heated Angora marble mosaic floors, walnut vanities and a freestanding Kallista soaking tub. Each secondary bedroom has an en-suite bath with Nestos marble and reeded walnut detailing. A Paonazzo marble powder room and dual-access laundry room with utility sink add convenience.
