Spectacular designer duplex in one of the foremost elegant and coveted buildings in New York. Designed by the world-renowned designer Vicente Wolf and featured on the cover of Elle Decor, every inch of this 12-room into 9-room residence has been masterfully conceived. Off a private elevator landing, the lower level of this grand home welcomes you with soaring 11-foot ceilings and a 29-foot central gallery from which all entertaining rooms flow. The dramatic corner living room and bay-windowed dining room merge seamlessly, enveloped by oversized picture windows overlooking the East River and Carl Schurz Park. There is a formal library with a wood-burning fireplace as well as a large bedroom/study with an en-suite full bath, all framed by the same sweeping views. The kitchen is a chef's dream, offering stainless steel appliances including a Traulson restaurant-quality refrigerator and Wolf 6-burner double-oven range with grill, custom wood cabinetry built up to the ceiling to optimize storage and a chic concrete counter and backsplash. The kitchen can be enjoyed open, or enclosed by a discreet sliding wall. On the upper level is a glorious Master bedroom suite featuring a large bedroom with another bay window, a separate sitting room with a fireplace, a dressing room, and a honed limestone bathroom with a window-framed double vanity and a glass-enclosed spa with limestone soaking tub and integrated shower. Off the master is a beautiful sitting room, originally a bedroom easily restored as such. There are two more bedrooms on this level, one with a separate private study and the other with wall-to-wall closets and built-in storage, plus two additional windowed bathrooms with contemporary tiling and concrete counters. There is also a huge laundry room with an industrial-sized washer and dryer, a professional laundry sink and walls of storage. There has been no luxury overlooked in the conception of this home. The floors are wide plank custom-colored White Oak, the multiple-zoned central air conditioning is temperature and humidity controlled and there is state of the art nuanced lighting control throughout. The building is 10 Gracie Square, an architecturally exquisite full-service cooperative built in 1930 and universally regarded as one of the most desirable buildings in Manhattan. It offers its 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 building flip tax of 3% payable by the purchaser.
