In the sub-Saharan region of Africa, and other parts of the world with similar climatic conditions and environments, this project aims to promote the construction of timberless vaulted mud brick houses which are environmentally friendly, affordable, and comfortable (compared to houses using expensive imported sheet metal roofing and timber beams), using a well-proven and easy to implement technique ('la Voute Nubienne', or VN). The VN technique, based on age-old methods from the Nubian region of Egypt, is relatively unknown in the Sahel. The project operates through demonstration (people seeing the VN houses being built and lived in), ?sensibilisation? (meetings, demos, films?) and on-the-job training of new apprentices on VN building sites. This training method is based on traditional, culturally embedded , methods of apprenticeship and skill development. The project is in many ways a text book example of South > South technology transfer. For more details, and a rich slection of photos and reports on the project, please consult our website at http://www.lavoutenubienne.org The site is available in French and English versions, and provides details of construction methods, basic house plans, photos of the exteriors and interiors of completed VN buildings, and technical reports.
