Developed in five phases between 1939 and 1948 as a residential community, the Westover Historic District provides an important example of the impact of New Deal programs on residential construction across the country and, in particular, Arlington County, where a surge of residential suburban growth occurred during the era. The modest Colonial Revival-style houses, garden apartments, duplexes, and twin houses, sited along winding streets, are indicative of the design standards specified by the Federal Housing Administration (FHA), which was established under the National Housing Act of 1934. The inclusion of commercial development and community facilities, restricted to major arteries, also illustrates the emphasis the FHA placed on safe and livable neighborhoods. The district’s early residential developments, including Westover Apartments (1939) and Westover Hills (1940-41), reveal the adoption of new building technologies such as Stran-Steel framing, concrete floors, and assembly-line construction methods.
