He also has improved the soil to decorate dwellings, and grown vegetables with soil composting techniques. By presenting four eco-houses, this paper analyses the practice of vernacular building in terms of sustainable use of materials, old building renovation, technique of earth ramming, and to solve the soil source, etc. His practice through soil reconstruction provides a high quality building mode that is cost effective, easy for construction, and energy efficient, and worth of spreading and learning.
