The Nubian Vault: for a solid, comfortable, and affordable home - FR / English Subtitles

Nowadays, because of climate change and deforestation, there's not enough locally available construction timber in the Sahel region of Africa. Traditional roofs are often replaced by imported corrugated zinc sheets and sawn timber frames - an expensive and climatically inappropriate solution. But with the Nubian Vault technique, using raw earth as the principal construction material, a building can go up without using timber Such buildings are well adapted to both rural and urban contexts.
