Natural building
A natural building involves a range of building systems and materials that place major emphasis on sustainability.

Ways of achieving sustainability through natural building focus on durability and the use of minimally processed, plentiful or renewable resources, as well as those that, while recycled or salvaged, produce healthy living environments and maintain indoor air quality.
Natural building tends to rely on human labor, on local ecology, geology and climate; on the character of the particular building site, and on the needs and personalities of the builders and users.
The basis of natural building is the need to lessen the environmental impact of buildings and other supporting systems, without sacrificing comfort or health. To be more sustainable, natural building uses primarily abundantly available, renewable, reused or recycled materials. Builders and homeowners are increasingly focusing on using renewable materials.
