This pleasant, brown-brick apartment building in the heart of the desirable Carnegie Hill neighborhood was erected in 1930 and converted to a cooperative in 1951. The 18-story edifice has 73 apartments. It was designed by Rosario Candela, who is widely considered to have been the country s greatest designer of luxury apartment buildings and he collaborated with many of the city's most famous architectural firms. He collaborated with Cross & Cross on the design of 720 Park Avenue and with Arthur Loomis Harmon on the design of 740 Park Avenue, two of the boulevard's most prestigious structures. He also worked with Cross & Cross on the design of 1 Sutton Place South and his other Park Avenue buildings include 765, 770, 778, 1021, 1172, 1192 and 1220. His other famous buildings include 834 and 960 Fifth Avenue and 19 East 72nd Street.Candela's buildings, "it is said, were the grandest of the decade that was itself the greatest," wrote Elizabeth Hawes in her book, "New York, New York, How The Apartment House Transformed The Life Of The City (1869-1930)", published by Henry Holt in 1993. "He had a respect for privacy and an eye for significant detail. He was a complete thinker. He added duplicate water connections to street mains and multiple switches for ceiling lights as well as beautifully turned staircases and separate wine cellars. More significantly, he designed buildings from the inside out. He placed windows where they received light, balanced a room, or allowed a graceful arrangement of furniture.... Candela also invested unusual energy in the entry hall. In a typical apartment, he made it a full-sized room with rich views into the interior because he thought it was important to greet a visitor with a full sense of a home.... Candela liked puzzles. During the Depression, he took up cryptography, and during World War II, he broke the Japanese code," Hawes wrote.Born in Sicily, Candela came to the United States in 1909 and graduated from the Columbia school of architecture in 1915. The building has a one-story rusticated limestone base and a canopied entrance beneath an attractive, rusticated limestone window reveal on the second floor and a very impressive and ornate limestone window reveal on the third floor flanked by female figures. The building, which also has four stringcourses and nice masonry quoins, has inconsistent fenestration and protruding air-conditioners. The first floor window sills have nice curved limestone brackets. There are many fine private schools in this neighborhood as well as many cultural and religious institutions. The building is not far from public transportation and excellent retail.
