Occupying the entire top floor of 550 Park Avenue and showcasing unparalleled city and Central Park views, this show-stopping, 4500 sq.ft. masterpiece represents the pinnacle of design meeting form and function. Offering 90' of Park Avenue frontage and soaring ceilings, this four bedroom, three and a half bathroom corner residence recently underwent a renovation that resulted in the addition of contemporary comforts and cutting edge technologies, while painstakingly maintaining original details and classic, quiet luxuries. This is a rare offering for only the most discriminating and rarified connoisseur. From the private, antique-mirrored landing, you are welcomed into the nexus of the home - a chic foyer enveloped in a glossy, glowing gray lacquer. Opening onto both the private and public spaces, this gallery features a stunningly-lit marble-clad powder room and an oversized coat closet. Through two distinguished raised doorways, the 63' long entertaining space is composed of a palatial living room with a marble-mantled, wood-burning fireplace that flows seamlessly to an enormous dining room, both with unobstructed Upper East Side views. Outfitted with custom Boffi cabinetry and honed Black Cosmic granite countertops, the windowed chef's kitchen boasts a suite of state-of-the-art Gaggenau and SubZero appliances, as well as a separate dining area. Custom Metalform Studio steel doors lead to a spacious serving kitchen that features more Gaggenau appliances, including two full-height wine refrigerators, and a gorgeously designed wet bar. With sweeping Park Avenue views, the primary suite is the epitome of elegance and comfort. A double-sided wood/burning fireplace separates the bedroom from a sophisticated sitting room. A huge dressing room with endless closets leads into a jaw-dropping, windowed ensuite bathroom clad in Keystone Aurora and Plumeria marble, and featuring an oversized floating bathtub, separate glassed-in shower and double vanity with Waterworks fixtures. The spacious second bedroom provides east and south exposures, while a third bedroom boasts Central Park views, as well as a wood-burning fireplace. A shared en-suite bathroom clad in Keystone Aurora and Arabescato marble features an enormous spa shower and brass Waterworks fixtures. The fourth and fifth bedrooms share a handsome Comet and Bardiglio Dark marble clad bathroom, and either could be re-appropriated as a home office. A laundry area with Miele washer/dryer, multi-zoned central air, a Lutron lighting system, radiant heat flooring and a Sonos music system round out the comforts of this incredible home.
