Compared with traditional buildings, prefabricated buildings can improve the quality of buildings, reduce the cost of construction projects, effectively shorten the construction period, and improve the efficiency of construction. Based on this, this article first introduces the concept of prefabricated buildings, secondly analyzes the growth and characteristics of prefabricated buildings, then discusses the prefabricated decoration, and finally puts forward suggestions to strengthen the rationalization of prefabricated decoration design, hoping to provide relevant industry professionals Some valuable references have laid a solid foundation for the rapid development of China's prefabricated construction industry.
