Mud Housing?

“MUD IS a versatile building material that has been used to make some extraordinary architectural marvels — from 1,000-year-old ksars (forts) in Morocco and 6,000-year-old arches, vaults and domes in the Nile Valley to multi-storeyed houses of adobe, sun-baked bricks of mud and straw, which is the traditional building material throughout much of Latin America.” (http://www.indiaenvironmentportal.org.in/content/19/mud-housing-is-the-key/)

“Mud is cheap, is a ‘breathable’ material and helps to maintain fairly even temperatures inside the house. Besides being eco-friendly, it is malleable and offers better insulation than concrete structures.” — Revathi Kamath
