The concept of the "Neighbourhood Unit" was developed by Clarence Arthur Perry in the 1920s. This concept aimed to design urban neighborhoods that are self-contained, with easy access to essential services such as schools, parks, and shops.
The Neighbourhood Unit concept emphasizes the idea of designing communities where most needs can be met within walking distance, promoting a sense of community and reducing reliance on cars.
The concept has been influential in urban planning, particularly in the development of suburban areas and planned communities.
