This paper examines tensions and frictions in urban planning and spatial practices of town inhabitants since the beginning of the 20th century in the town of Kasba Tadla, an ordinary town in the Middle Atlas Region. It shows how Moroccan towns and cities have been divided into quarters; while some offer all amenities of modern urban life, others, built by the residents themselves, were officially disregarded. From the end of the 20th century onwards, this distinction has been changing towards a more equal distribution of resources. The author suggests a thorough reflection of professional action and proposes that urban planning be rooted in the local context in connection with colonial, national and global influences. Urban development that recognises town people as active partners in the production of urban space is encouraged.
