A distinguished Upper East Side townhouse with more than a century of architectural history, 126 East 73rd Street offers a rare combination of pedigree, scale, and turnkey livability. Originally built in 1873 in the Italianate style and transformed in 1912 by architect Benjamin H. Webber into its present neo-Elizabethan style, this five-story, nearly 19-foot-wide residence has been impeccably renovated and meticulously maintained by its current owners. It is presented in true move-in condition. Ideally positioned on a prime tree-lined townhouse Lenox Hill block between Park and Lexington Avenues, the home spans approximately 6,250 square feet, with a 1,130-square-foot finished basement, plus a 720-square-foot spectacular private landscaped garden with fountain.
