Although only 12-stories tall, this building, which was erected in 1912 and converted to a cooperative in 1948, conveys an impressive sense of monumentality. It has 50 apartments. The beige brick building, which has a two-story limestone base, was designed by George and Edward Blum, whose other Park Avenue structures include 555, 591, 830, 840, 940 and 1075. This building has some attractive balconies with small but nice wrought-iron railings and an interesting roofline that abstractly resembles battlements. The building has consistent and attractive multi-paned fenestration and some protruding air-conditioners. There are steps up into the lobby and the building has some sidewalk landscaping. The building is convenient to many boutiques and art galleries along Madison Avenue, numerous restaurants in the area and a local subway station on Lexington Avenue at 77th Street. Cross-town buses run on 79th Street one block to the north and Lenox Hill Hospital is one block south.
