After World War II, due to the widespread impact of war on buildings on the European continent, they suffered heavy damage and were unable to provide normal living conditions, as well as a shortage of labor resources. At this time, there was an urgent need for a new construction method with fast construction speed and less labor occupation to meet the short-term demand for housing in various countries. As a result, prefabricated buildings began to emerge abroad..

In the 1960s, prefabricated housing was widely promoted, with the proportion of prefabricated housing accounting for 18% to 26% in the mid-1960s. In the 1980s, prefabricated housing in East Germany increased to 80%, prefabricated housing in Poland increased to 80%, and prefabricated housing in the former Soviet Union increased to 55%..

In 1976, the National Industrial Housing Construction and Safety Act was passed in the United States Congress, and a series of strict industry standards were introduced. In 1991, the United States proposed the development of prefabricated buildings as an opportunity for the development of the American construction industry. Currently, the proportion of prefabricated buildings in the United States accounts for about 35%..

The research on prefabricated buildings in Japan began with the establishment of the Japanese Housing Corporation in 1955. In the mid-1960s, prefabricated housing in Japan made significant progress, with the production of prefabricated components forming an independent industry. In 1973, the establishment of the prefabricated housing access system marked the beginning of prefabricated housing as a systematic building. From the late 1950s to the late 1980s, a relatively mature prefabricated residential structural system was formed. By 2001, Japan had approximately 30 million square meters of newly completed prefabricated housing each year..

The development of prefabricated housing in developed countries and regions has roughly gone through three stages: the first stage is derived from market demand, that is, in the early stage of the formation of prefabricated buildings, the focus is on establishing a production (construction) system for prefabricated buildings; the second stage is the development period of prefabricated buildings, gradually improving the quality and cost-effectiveness of products (residential); the third stage is the mature stage of the development of prefabricated buildings, driving market demand, Further reduce the material consumption and environmental load of residential buildings, and develop green buildings..

From the perspective of the development of prefabricated buildings in various countries, there is a clear timeline. Although prefabricated buildings in China have just started, they have advanced foreign technology and successful experience. We can also avoid detours and vigorously promote the development of prefabricated buildings. This is not only a path of transformation in building methods, but also a long-term development path of green and environmental protection..
