1937 - United Workers Cooperatives, also known as Allerton Coops, is a historic apartment building complex located at 2700-2870 Bronx Park East. The complex includes three contributing buildings and five contributing structures. The Tudor Revival style buildings were built during two construction campaigns, 1926-1927 and 1927-1929 by the United Workers' Association. Though considered a social success, the complex failed financially in the Great Depression and was converted to rental housing in 1943. After decades of neglect by a succession of landlords, the complex was purchased and renovated by a new owner in the mid-1980s. The complex was listed on the National Register of Historic Places in 1986, and was designated a National Historic Landmark in 1991. It was designated a New York City landmark in 1992.
