Natural materials

A product that is made from materials and ingredients found in nature, with little or no human intervention. Natural materials include stone, glass, lime or mud plasters, adobe or rammed earth, bricks, tiles, untreated wood, cork, paper, reeds, bamboo, canes and grasses as well as all natural fibers. From both an aesthetic and health point of view, building with natural materials also helps sustainable development.
