This handsome apartment has many similarities with the building directly across 76th Street, 830 Park Avenue: they were built in the same year, 1912, designed by the same architects, George and Edward Blum, and converted to a cooperative in the same year, 1953. The buildings, however, are quite different in color, massing and size. This one is light-colored, has no center "light well," and has 53 apartments. 830 is darker, has a center "light well," and has 78 apartments. The avenue facade on this building is also more formal with a nicely symmetrical placement of balconies and an arched entrance. The building has a rusticated limestone base and some attractive wrought-iron balconies. It has protruding air-conditioners, but almost all of its windows are still, thankfully, multi-paned. Unfortunately, this 12-story-building has a fuller view from many of its apartments of the jarring "pink" pavilion of Lenox Hill Hospital directly across the avenue than 830.This building is close to many fashionable restaurants, boutiques and art galleries along Madison Avenue and is down the sidestreet from the elegant entrance to the Carlyle Hotel. The architects, George and Edward Blum, also designed 555, 791, 940 and 1075 Park Avenue. A local subway station is at 77th Street and Lexington Avenue and cross-town buses run on 79th Street.
