Terraced houses have been popular in the United Kingdom, particularly England and Wales, since the 17th century. They were originally built as desirable properties, such as the townhouses for the nobility around Regent's Park in central London, and the Georgian architecture that defines the World Heritage Site of Bath.
The design became a popular way to provide high-density accommodation for the working class in the 19th century, when terraced houses were built extensively in urban areas throughout Victorian Britain. Though numerous terraces have been cleared and demolished, many remain and have regained popularity in the 21st century.
