Community architecture emerged in response to issues like the growth of slums and poor urban planning. It aims to directly involve community members in designing and building housing and neighborhoods. The movement began in the late 18th century during industrialization and gained prominence in the post-WWII period in the UK and US. Key figures like Rod Hackney and Charles Knevitt advocated for community participation in planning and the right to have a say in one's living environment. Community architecture stands in contrast to conventional or top-down approaches by actively engaging end-users throughout the entire design and development process.
