Prior to the American Revolution, colonial America derived its public buildings from architectural styles and practices of Great Britain. After gaining independence, the American republic was influenced and inspired by classical Roman and Greek forms, representing the democratic ideals of law and citizenship of a new nation. In 1852, after the population tripled in numbers, the Office of Construction and Office of the Supervising Architect were established under the Treasury Department to oversee federal design and construction and make the process more efficient and timely. Designs in this period moved away from classicism toward other styles like
Renaissance Revival, and emphasized centralization and standardization. While there is no universally accepted start date for federal modernism, in the early twentieth century the materials and building methods used in federal buildings changed, and reflected the styles of early modernism. These buildings utilized clean lines, flat surfaces, and simple geometric shapes, lacking the ornamentation prevalent in classical architecture. While classicism asserted permanence and authority, modernism celebrated innovation and freedom with its steel and glass materials. During the
New Deal, approximately 1,300 federally funded buildings were constructed nationwide in a simplified classic style. Sometimes referred to as "modern classic" or "stripped classic mode, the "style was so named because the basic form and symmetry of classicism were retained, but much of the ornamentation and motifs were reduced or removed." After the General Services Administration (GSA) was established in 1949 to "provide the resources needed by U.S. agencies to accomplish their missions," federal buildings reflected an emphasis on functionalism rather than ornamentation. Federal modernism is most closely associated with the GSA buildings constructed between the 1950s and 1970s, which embodied this philosophy. Trends of functionalism included individual offices becoming less common while large open "universal" spaces became more common. == Characteristics ==
