Description
Welcome to the pinnacle of luxury living at Penthouse 48, an extraordinary full floor residence spanning 4,628 square feet with show-stopping 360-degree views of Central Park and New York City’s iconic skyline. Ideally situated in the Upper East Side’s most distinguished address, an exceptional limestone-clad condominium crafted by world-renowned architect Robert A.M. Stern, this magnificent sundrenched 48th floor masterpiece is one of the highest positioned simplexes and one of the few with soaring 15-foot ceilings at 520 Park Avenue. Enter from your private key-locked elevator landing through stately double doors into an impressive gallery from which all interconnected entertaining spaces graciously flow. Experience the magic of New York City from sunrise to sunset from the grand corner living room, featuring breathtaking views of Central Park, the Madison Historic District, and the East River through walls of expansive windows. Separated by oversized pocket doors, the living room opens into the spacious formal dining room (currently utilized as a second living room) with more sweeping views. Adjacent to the living room is an intimate media room/library which could easily function as a 4th bedroom with its gorgeous ensuite marble bathroom. The spectacular windowed eat-in-kitchen overlooking Central Park is outfitted in custom Christopher Peacock cabinetry and hand painted cabinets with hand-blown glass. The best-in-class appliance package boasts a Subzero refrigerator with two freezer drawers, two additional separate refrigeration drawers, a six-burner plus skillet Wolf range with vented hood, two Miele dishwashers, multiple Wolf wall ovens, built-in below-cabinet Wolf microwave, and a full-height Sub Zero wine refrigerator. Enjoy your morning coffee from the beautiful island cloaked in marble or in the breakfast nook with mesmerizing views west through floor-to-ceiling windows. The luxurious corner primary bedroom suite boasts sunlit south and east exposures with incredible views of the Empire State and Chrysler Buildings, four closets, two of which are custom-outfitted walk-in-closets, and a spa-like windowed bathroom with Victoria Albert free-standing bathtub, separate steam shower, radiant heated floors, stunning marble slabs and fixtures, and a custom-designed double vanity. A second private bedroom corridor separates the second- and third-bedroom suites from the public rooms and contains the in-unit laundry, featuring an Electrolux washer and vented dryer. Both bedrooms enjoy natural light pouring through southern and western windows, an abundance of closet space, and ensuite marble bathrooms, one with a tub and the other with a glass stall shower. Additional notable features of this elegant oasis in the sky include a full guest bathroom off the entrance gallery, select-cut solid white oak hardwood flooring in classic herringbone and overlay patterns, custom crown molding, and multi-zone central air conditioning and heating with precise temperature control in every room. There is also a storage unit that will transfer with the sale. With only 35 residences, 520 Park Avenue offers white-glove service and an unmatched suite of amenities including a full-time doorman and concierge, a magnificent lobby, beautifully landscaped garden, a spectacular two-story fully-equipped fitness center with private training rooms and a pilates studio, double height 25-meter indoor swimming pool, a serene spa retreat complete with sauna, steam rooms, and private treatment suites, multiple dining and entertaining spaces including a grand salon, library, and screening room, private office/work spaces, wine cellar, cold storage, and bike storage. Ideally nestled among prominent museums, luxury boutiques, charming cafes, and the world’s finest restaurants, 520 Park Avenue offers prestigious living and historic neighborhood charm right on your doorstep.
