834 Fifth Avenue is a luxury residential cooperative building located opposite the Central Park Zoo. The limestone-covered building is widely regarded as one of the most prestigious apartment houses in New York City. Built in 1931, it is considered one of the finest buildings architect Rosario Candela designed. Elements of Art Deco styling were utilized on the entryways and portions of the Fifth Avenue façade, and setbacks at the upper floors create terraces for several apartments. The building has 24 spacious apartments (ranging in size from approximately 4,000 square feet to well over 7,000 square feet.) on 16 floors. The largest single unit is approximately 12,000 square feet. The apartments have 11-foot or greater ceiling heights and very few apartments have layouts similar to another. There are three maisonette units with private entrances as well as entrances from the building's lobby. The upper floors contain mostly duplex units and one triplex. As a matter of fact, the entire 64th St. side of the building is composed of duplex apartments. These units have large entertaining rooms and four to six bedrooms.
