38 East 63 Street   Unit HOUSE

Built in 1880 bу acclaimed architect F. S. Barus, 38 East 63rd Street is a Neo-Georgian townhouse that is 18 feet wide and about 7,155 square feet above ground. It features flexible open office spaces, plus an additional 1,545 square feet on the lower level for storage and mechanical systems. The property is ideally located between Park and Madison Avenues on a quiet, tree-lined block with historic homes.
The building's facade was redesigned in 1904 by architect William Strom in an elegant Neo-Georgian style for banker John Greenough and his family. The distinctive facade features a gracefully bowed front across the first three levels, anchored by a limestone base with finely detailed window surrounds and trim, along with a classic balcony that enhances its refined architectural presence.
The composition subtly echoes the superb Cross &Cross Neo-Georgian facade of the grand 40-foot-wide mansion at 36 East 63rd Street next door, built in 1930, creating a harmonious architectural dialogue between the two neighboring residences and reinforcing the historic elegance of this exceptional block.
