One of Park Avenue s more exclusive apartment buildings with only one unit per floor, this 13-story, limestone-clad building was erected in 1914 and converted to a cooperative in 1946. It was designed by J. E. R. Carpenter, the leading architect of luxury apartment buildings in the city of his generation. His other Park Avenue buildings include 550, 580, 625, 630, 635, 655, 812, 950, 960 and 1050. His Fifth Avenue buildings include 810, 825, 907, 920, 950, 988, 1030, 1035, 1060, 1115, 1120, 1143, 1150, 1165 and 1170 as well as 2 East 66th Street. The building, which has a sidestreet entrance with a very impressive entrance, was developed by S. Fullerton Weaver and replaced six row houses. Some of the apartments have as many as 18 rooms and most have cedar closets and fireplaces. The building has protruding air-conditioners. This section of Park Avenue is very desirable because it has several very handsome low-rise buildings, churches and landmarks that make it architecturally quite interesting and also provides more open views. This building is across the avenue from the imposing and impressive 7th Regiment Armory. It is also convenient to public transportation and the many fashionable boutiques and restaurants along Madison Avenue and, of course, it is not too far from Central Park.
