3 East 63rd Street is a 25-ft wide townhouse, which is ideally located between Fifth and Madison Avenue, feet from Central Park, Madison Avenue shops, gourmet stores, restaurants and other requisite neighborhood conveniences.Situated in a Manhattan Landmark Historic District on one of the Upper East Side's premiere townhouse blocks, the property is currently configured as 11 units on five floors, featuring high ceilings throughout including 14 ft. on the second floor. There are six wood burning fireplaces, too.As well as several other houses on the street, developer William Parsons built this house for himself in 1880. The current building totaling 9,975 sq. ft. retains the full-height projecting bay and original scale. It has been suggested that lot line windows on the western wall of the building might be added to further illuminate the interior of the house.Although located in a landmark district, the house itself is not a landmark. Thus, the new owner can renovate the interior with great freedom (subject to New York City building codes). This presents a rare opportunity to either convert it back to a single family home, in any style, or renovate into a multi-unit home that is complementary to 21st century living.
