A breathtaking duplex that unfolds magnificently over a 4,346 square foot configuration, the singular Penthouse at the Touraine has been designed for the finest in both living and entertaining. Set atop a prominently located boutique Upper East Side condominium, this is a stunning, mint condition, one-of-a-kind home. Featuring 50 linear feet across the den, living, and dining rooms, coupled with a ceiling height of nearly 11 feet, the main floor enjoys stunning views to the north, as well as west toward Central Park. A gourmet kitchen features honed Italian Calacatta marble, several Gaggenau appliances, and a beautiful windowed eat-in, breakfast area. The refrigerator and wine fridge are by Subzero. The main floor also boasts a den, which can serve as a guest room, complete with an en suite windowed bathroom, and a fantastic powder room. On the upper floor, a sun-soaked primary bedroom occupies the prime corner and includes one of the most attractive and thoughtful, custom walk-in closets imaginable, naturally with a window of its own. A luxurious and windowed master bathroom is outfitted with Waterworks fixtures, Italian Calacatta and Arctic gray marble, and a freestanding soaking tub, as well as a ribbed-glass enclosed shower and separate enclosed Toto toilet. Additional closets and storage were added throughout this master suite. The windows face north and west with views of Central Park. Two of the three additional bedrooms, each with an en suite marble and Waterworks bathroom, face north, while the fourth bedroom nestles at the opposite corner and benefits from north and east exposure. Notably, each of these rooms offers unusually generous dimensions and a sense of freedom further accented by the 11-foot ceilings. The Penthouse has its own private roof deck with stunning views of Manhattan, a private wine locker for over 100 bottles in the wine cellar, and an oversized private storage unit. This magnificent home is prewired for a smart home system of your choosing with full audio-visual control, including the in-wall speakers, electric shades, lighting, and full command of the multizone HVAC. There is also a Lutron system to independently control the lighting and shades. The floors are 5" plank ash wood, the windows are oversized, there is a spacious laundry room with washer/dryer, and there is a convenient storage room just off the kitchen. The Touraine features the amenities and luxury of a new development while maintaining a discreet, boutique feel. A gorgeous marble lobby, staffed by 24-hour concierge, and a residents' library are stylized and sophisticated. Owners avail themselves of a beautiful barrel-vaulted wine cellar with fireplace, a well-equipped and conceptualized fitness center, plus a landscaped roof-top terrace. The Penthouse at the Touraine is a property that must land on the short list for the serious buyer.
