Brighton and Hove, a city on the English Channel coast in southeast England, has a large and diverse stock of buildings "unrivalled architecturally" among the country's seaside resorts. The urban area, designated a city in 2000, is made up of the formerly separate towns of Brighton and Hove, nearby villages such as Portslade, Patcham and Rottingdean, and 20th-century estates such as Moulsecoomb and Mile Oak. The conurbation was first united in 1997 as a unitary authority and has a population of about 253,000. About half of the 20,430-acre (8,270 ha) geographical area is classed as built up.

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.
