“The label “natural building” can refer to a wide variety of construction methods and materials. The natural buildings that we build at Earth Home are made from wood, clay, sand, rice husks, straw and water. Some cement is used in the foundation of the buildings. Since roofs are the most expensive element in the entire construction, corrugated roof sheets made from aluminum or cement are used when the more expensive wooden, bamboo and straw (thatch) roofs are not affordable.
If you are interested, we will teach you all it takes to create a beautiful building out of mud, from foundations to orientation, roofs to wall structures. When you come for a Natural Building workshop, you will gain hands-on practical experience throughout the workshop.”
