This incomparable full-floor residence by AD100 firm Ashe Leandro offers exquisite design, tranquil treetop views, private outdoor space, and a sought-after key to Gramercy Park. Currently configured as a generous two bedroom plus library with two and a half baths, each moment in this apartment was carefully crafted to provide decidedly elegant yet relaxed living spaces. A direct elevator entry opens onto a wide gallery, dividing public and private spaces. The living room is perfectly proportioned and features a full wall of glass overlooking Gramercy Park below, as well as a gas fireplace clad in marble, intricately-patterned parquet de Versailles hardwood floors, and custom moldings. The custom lacquered library is adjacent and extends across the unit's 27 feet of width, with perfect park views and a chic powder room. The formal dining room is wrapped in custom moldings and has a custom lacquer bar, perfect for beverage and stemware storage and display. An elegant kitchen is discreetly located off the dining room, complete with custom cabinetry, marble and butcher block countertops, a range by Lacanche, and refrigeration by Sub-Zero. The home's primary bedroom suite is absolute perfection, with a gas fireplace clad in vein-cut limestone, multiple closets including a large walk-in, and a chic en-suite bath finished in Carrara marble with radiant heated mosaic tile floors, double sink vanity, a clawfoot soaking tub, oversized shower, and brass fixtures throughout. A private solarium extends the primary suite and is perfect for a sitting room or office and provides access to the private terrace with stone flooring and a custom trellis by Harrison Green. The second bedroom also has access to this lovely outdoor space and has access to a second full bathroom with vintage-inspired finishes. Central HVAC, a built-in Savant system, central humidification, washer/dryer, and designer lighting controls complete this turn-key residence.
