Description
The Carlton House spans the full Madison Avenue blockfront from East 61st to East 62nd Street, just one block from Central Park. Once the Helmsley Carlton House, the building was reimagined by Extell in 2015 as a collection of refined modern residences. This high floor two bedroom, two bath home is finished with care throughout. White oak floors run through every room, custom millwork adds warmth, and a Lutron system controls motorized solar shades and blackout shades. The open kitchen pairs white lacquer cabinetry with a full suite of Miele appliances and a Subzero wine cooler. The primary suite has two large custom closets and a marble bath with double sinks, a rain shower, a soaking tub and heated floors. Off the bedroom is what sets this home apart, a private terrace of roughly 100 square feet with open views south toward downtown and east over Madison Avenue. The second bedroom works just as well as a library, with a double closet and a hall bath that also has heated floors. A Miele washer and dryer and central air complete the home. Residents enjoy a white glove doorman and concierge, a resident manager, a 65 foot heated indoor pool, steam rooms, a playroom, private storage, bike storage and a refrigerated room in the lobby for grocery deliveries. With Central Park a block away, as well as Bergdorf Goodman, Hermès, Chanel, Apple, Tom Ford, Cipriani, La Goulue and Bilboquet. Ground lease expires June 30, 2169.
