Generally, you should start building a house within two years, and you can't stay idle all the time.
According to the Land Administration Law of the People's Republic of China, the Property Law of People's Republic of China (PRC) and the Construction Law of People's Republic of China (PRC), the validity period of both the homestead building permit and the agricultural land building permit is two years, and an extension can be applied after the expiration, and each extension is limited to three months and cannot be extended twice.
The main body of rural self-built houses is generally capped. In fact, after the roof is watered, it takes at least one month to dismantle the formwork, usually one and a half to two months. For example, in cold winter, there is less sunshine and the weather is colder, usually more than two months later. Dismantle the formwork too early, lest the roof knot is not good enough, which will affect the overall structure and safety.
