NEW EXCLUSIVE: A grand and sprawling four or five bedroom corner duplex apartment overlooking the East River in one of the city's most beautiful and coveted buildings, 10 Gracie Square. Off a private elevator landing, a beautifully proportioned foyer leads to a double-sized living room pouring over the East River, with a large private balcony perfect for evening cocktails, a wood-burning fireplace and stunning herringbone hardwood floors. To one side of the living room is a formal dining room which can easily seat 20, also with magical river views, and to the other a gorgeous wood-paneled corner library with another wood-burning fireplace, wet bar and elegant guest bathroom, offering South and East views over the river as well as access to the balcony as well. There is a butler's pantry with marvelous storage and a washer and dryer, a second guest bathroom, and an enormous double-sized windowed eat-in chef's kitchen, with a built-in dining area, custom wood- and sand-blasted glass cabinets, stone floors and counters, top-of-the-line appliances including two refrigerators, a separate freezer, two ovens, a six-burner professional grade stove and massive storage. A handsome staircase leads to the upper level bedroom floor which offers five stately bedrooms off a central level hall. The corner Master bedroom suite offers South and West exposures, a large walk-in closet and the property's third wood-burning fireplace. Off the Master bedroom is a second bedroom currently serving as the Master's home office but easily restored for private bedroom use. The remaining three bedrooms are all graciously proportioned and each have their own en-suite bathroom and walk-in closet or walls of closets - the closet space is phenomenal throughout. Additional features of this baronial home are soaring 11-foot ceilings, glorious prewar detail and discreet through-wall air conditioning. It also comes with a separate 9'x12' private storage room downstairs. 10 Gracie Square is an architecturally exquisite full-service cooperative built in 1930 and universally regarded as one of the most desirable buildings in Manhattan. It offers its discerning residents full-time lobby attendants, a live-in resident manager, a private drive-through breezeway, private storage, bicycle storage and its own indoor basketball/squash court. Pets are welcomed and there is a 3% flip tax, payable by the purchaser.
