Federal (style)

Federal-style architecture is the name for the classicizing architecture built in the newly founded United States between c. 1780 and 1830, and particularly from 1785 to 1815. This style shares its name with its era, the Federal Period. The name Federal style is also used in association with furniture design in the United States of the same time period. The style broadly corresponds to the classicism of Biedermeier style in the German-speaking lands, Regency architecture in Britain and to the French Empire style.

In the early American republic, the founding generation consciously chose to associate the nation with the ancient democracies of Greece and the republican values of Rome. Grecian aspirations informed the Greek Revival, lasting into the 1850s. Using Roman architectural vocabulary, the Federal style applied to the balanced and symmetrical version of Georgian architecture that had been practiced in the American colonies' new motifs of neoclassical architecture as it was epitomized in Britain by Robert Adam, who published his designs in 1792.

American Federal architecture typically uses plain surfaces with attenuated detail, usually isolated in panels, tablets, and friezes. It also had a flatter, smoother façade and rarely used pilasters. It was most influenced by the interpretation of ancient Roman architecture, fashionable after the unearthing of Pompeii and Herculaneum. The bald eagle was a common symbol used in this style, with the ellipse a frequent architectural motif.

The classicizing manner of constructions and town planning undertaken by the federal government was expressed in federal projects of lighthouses and harbor buildings; hospitals; in the rationalizing, urbanistic layout of L'Enfant's city of Washington; and in New York the Commissioners' Plan of 1811.
