At present, the level of development of housing industrialization in China is still at the primary stage, the traditional design method and mode of production has restricted the development of residential industrialization.So changing the traditional ways of design and reducing the cost of construction industrialization become the main task. Using the modular design method based on BIM in the prefabricated housing design and combining construction drawing design with resolution to deepen the design process in the traditional residential industry can optimize design process and improve the efficiency of design. Through detailed research on prefabricated components design and production enterprises and construction enterprises, and research on the application of BIM on the module, this paper puts forward a suitable assembly type structure based on the modularization design method of BIM. The"building block" method is used to make the model unit and form the whole building model. This method can improve the design efficiency, save the cost of design, and improve the entire building industrialization production chain.
