The Maisonette at The Park Mansion is an exceptional three-bedroom, 3+ bathroom duplex that sprawls over approximately 3,550 sq.ft., boasting a 770 sq.ft. private garden. Boasting high ceilings and the finest finishes and fixtures, this gorgeous, turn-key home is available to only the most discerning buyer. A keyed elevator ushers you to a private foyer, from which you enter the gallery which connects the private and public areas of the home. A huge living room with herringbone White Oak flooring evokes a greenhouse effect with its wrapped windows that open onto a huge private garden. The great room is large enough to comfortably accommodate a large dining area as well as ample living room. The adjacent, windowed Arclinea chef’s kitchen features Quartzite counters, including a suite of Miele appliances, a waterfall edged breakfast bar and custom cabinetry. The spacious primary suite features floor-to-ceiling windows that open onto the private south-facing garden. The large Calacatta-clad ensuite bathroom boasts a stunning soaking tub, a separate shower and separate WC, as well as Bardiglio white marble flooring with radiant heat. Another large bedroom sits across from the primary and looks onto the garden, while the third bedroom sits on the north side, past the kitchen. Both bedrooms boast elegant ensuite bathrooms and oversized closets. Accessed via a stylish glass and wood floating staircase, the expansive, skylit lower-level spreads over a large, open entertainment area. Two fully finished storage areas sit adjacent and are fully enclosable. Wide-plank White Oak flooring throughout, ample closet and storage space, and two Electrolux stacked washer/dryers round out the thoughtful amenities of this exceptional residence. Constructed in 1900, The Park Mansion is a Beaux-Arts-style landmarked building on a quiet, tree-lined Upper East Side block. Building conveniences include a full-time doorman, a fitness room and bicycle storage.
