730 Park Avenue New York located on Park Avenue between 70th and 71st Streets, this 20-story apartment building was built in 1928 and converted to cooperative in 1945. Designed in the neo-Renaissance and neo-Jacobean style by architect Lafayette A. Goldstone, 730 Park Avenue’s forty residences span six to sixteen rooms and measure 1,800 to 6,000 square feet. The majority of homes are duplex residences. Architectural features found throughout the building include outdoor spaces ranging from small balconies to large terraces—wood burning fireplaces, gracious proportions and elegant ceiling heights. 730 Park Avenue is positioned between 740 and 720 Park Avenue, amidst what is considered the most desirable stretch of Park Avenue, from 70th to 73rd Streets. These blocks represent the concentrated product of the golden age of New York apartment house construction, and are now one of the densest groupings of existing, storied apartment houses in Manhattan. The decision to build in this location was the result of its topography, as this area sits at one of the highest elevations on the avenue south of 79th Street. As a result of this height, apartments at 730 Park Avenue boast wonderful light and open city exposures—including Central Park views from the upper stories of the building—an extremely unusual characteristic for a Park Avenue locatio:
