Extraordinary renovation of an 1898 carriage house on the Upper East Side "carriage house block". East 73rd Street, which has been noted by the New York Times as one of the most distinctive in New York, is replete with low rise carriage houses that were originally used by the most wealthy residents of the Upper East Side. Formerly occupied by two world class foundations, this property comprises over 5,000 square feet and offers a spectacular move in installation or an ideal canvas for conversion to a single family home. The parlor floor welcomes in a tremendous amount of light from the grand ceiling heights (approximately 13ft) and large windows leading out to the balcony. The basement and parlor floors are currently facilitated as top notch office space, ideal for an art gallery or similar business. The home also encompasses two apartments on the top two levels which allow for the perfect live-work situation. On the third floor you will find two massive terraces offering approximately 1,400 square feet of outdoor space overlooking the beautiful historic block. The unique heating system is worth noting as the air is relayed by aesthetically pleasing platinum structures throughout. The home also features two entrances, one being from the large carriage house doors and another from the side door leading into the vestibule allowing for ultimate privacy between the office and residential spaces. The modernized facade is designed in a beautiful Beaux-Arts style set on a limestone base while still preserving the original Romanesque details. This magnificent 15 room home includes 2 kitchens, 2 kitchenettes, 3 full baths, 3 half baths, and 2 bedrooms.
