Federal-style architecture is the name for the classicizing architecture built in
North America between c. 1780 and 1830, and particularly from 1785 to 1815, mostly from the two brothers,
Robert Adam and
James Adam. 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 style in Britain and to the French
Empire style.
