Eco-friendly house is not only useful, but also economical structure.
Using natural materials to build a house, you can save a lot on them. Extruded straw blocks, which cost hundreds of times cheaper than bricks, are considered to be the most environmentally friendly material, and due to their light weight, they can also make the foundation construction cheaper. Such material does not require powerful and expensive mechanisms for installation, and also keeps heat well, has high sound insulation.Housing from adobe (a mixture of straw and clay) also has a low thermal conductivity and good sound insulation. Adobe house is not only one of the cheapest, but also durable.
