This is a magnificent opportunity to own a 4,700 sf, 5-bedroom, spectacular home with design features from a world renowned architect in a unique boutique condominium building that provides the intimacy of a private residence but offers the finest white glove services including a full time concierge, resident manager and porter.    Residence 2/3 is a meticulously renovated home, with some exquisitely designed elements by Maya Lin, the architect of the Vietnam Memorial Museum. It offers an amazingly versatile layout with two levels of expansive and architecturally striking public areas for formal entertaining or luxurious casual living, a very private master bedroom suite with its own patio, a separate 3-bedroom wing and approximately 460 sf of outdoor space designed by David Giovannini, which, together with the apartment, has been featured in numerous design magazines. Other features include a wood burning fireplace, beautiful Anigre maple flooring, Sycamore paneling, exquisite baths, and top of the line appliances in the kitchen including washer/dryer. Two storage bins come with the apartment.    The Curzon House is a 13-unit, full service condominium building that was created from the merging of several historic Beaux Arts mansions in this most desirable block filled with palatial homes, between Fifth and Madison Avenues, and near some of the city's finest restaurants and boutiques, including Cipriani, Nello, Le Bilboquet, Barneys New York, Hermes, and Bergdorf Goodman.
