Natural building is a type of construction that uses natural materials instead of man-made materials. These natural materials could be things like clay, earth, sand, straw, and stone. Natural building is usually done by people who want to build a house that is eco-friendly. Natural building can be used to make structures which are strong and durable without using a lot of energy or causing damage to the environment. Natural building also looks nicer than regular building because it uses more natural shapes and materials, making it more beautiful.
