What are the precautions for building your own house?

1. The terrain of the land is Gao Shuang with abundant sunshine and low groundwater level, and the ground should have a certain slope. This is conducive to drainage, moisture-proof, keeping the ground dry, enhancing the anti-corrosion ability of the house, while keeping the environment clean and reducing the breeding grounds of flies and mosquitoes. If the terrain conditions are not ideal, artificial improvement can be made. Many ancient villages are built by mountains and rivers, and the rain on the mountains falls down the slope (that is, "shower head water" in geomantic omen). Part of it is collected by ditches, and part of it seeps into the ground and invades the foundation of the house. The room is very humid, and you will get rheumatic diseases if you live for a long time. Severe cases will increase the incidence of rheumatic heart disease, tonsillitis and pharyngitis. In this case, deep ditches can be dug around the house to drain water and improve the environment. 2. Saving cultivated land: Due to the population growth, the per capita cultivated land area in rural areas is decreasing year by year, which affects the production of grain and produces a large number of rural surplus labor, which is nowhere to be used. Rural housing occupation of fertile land has become the main reason for the reduction of agricultural arable land. This requires that the choice of residential land should occupy less or no cultivated land, woodland and artificial pasture, but try to choose wasteland and hillside. In particular, the building materials are good, such as reinforced concrete, which has strong wind disaster resistance and can be less restricted by terrain conditions. 3. Houses should try to avoid areas where railways, highways and high-voltage transmission lines pass, and also avoid places where underground resources or important historical sites have been proved to be exploitable.
