How was the british planning development in 17th-20th century?

British planning development from the 17th to the 20th century evolved significantly, reflecting social, economic, and political changes. In the 17th century, urban growth was largely unregulated, leading to overcrowded and unsanitary conditions. The Industrial Revolution in the 19th century prompted more organized planning, as cities expanded rapidly; this led to the establishment of public health measures and infrastructure improvements. By the 20th century, town planning became formalized with the introduction of comprehensive planning laws and the establishment of various planning authorities, emphasizing zoning, community needs, and environmental considerations.
