Regency architecture encompasses classical buildings built in the United Kingdom during the Regency era in the early 19th century when George IV was Prince Regent, and also to earlier and later buildings following the same style. The period coincides with the Biedermeier style in the German-speaking lands, Federal style in the United States and the French Empire style. Regency style is also applied to interior design and decorative arts of the period, typified by elegant furniture and vertically striped wallpaper, and to styles of clothing; for men, as typified by the dandy Beau Brummell and for women the Empire silhouette.
The style is strictly the late phase of Georgian architecture, and follows closely on from the neoclassical style of the preceding years, which continued to be produced throughout the period. The Georgian period takes its name from the four Kings George of the period 1714–1830, including King George IV. The British Regency strictly lasted only from 1811 to 1820, but the term is applied to architecture more widely, both before 1811 and after 1820; the next reign, of William IV from 1830 to 1837, has not been given its own stylistic descriptor. Regency architecture is especially distinctive in its houses, and also marked by an increase in the use of a range of eclectic Revival styles, from Gothic through Greek to Indian, as alternatives to the main neoclassical stream.
