American Architecture: The Elements of Federal Style.
Federal home design style comes with another confusing name. In design, the word "federal" simply indicates the time period (1780–1820) when the style, known among architecture aficionados as the American phase of the Adam style, prevailed in the fledgling United States. The style borrowed heavily from contemporary European influences, particularly the English Adams brothers. The brothers had traveled to Italy and are credited with popularizing architectural details from original Roman and Greek buildings instead of their Renaissance interpretations.
There's also a townhouse version in federal architecture. Many original Adam townhouses, both attached row houses and narrow detached urban houses, still exist. They're concentrated in cities like Boston, Philadelphia, Georgetown and Savannah.
Townhouse developments are becoming increasingly popular as part of an effort to conserve space and facilitate pedestrian zones. Most such developments built today are modeled on federal style.
