Abstract：
Modular building is a new type of prefabricated building with high industrialization level. The status and issues about modular buildings in China were first discussed in this paper and the first officially approved modular steel residential building in China was introduced. Based on the project, key technologies were clarified all-roundly in terms of architectural design, structural design, envelope system, industrial manufacture, transportation and on-site installation, providing rich experiences for design and construction of multi-storey and high-rise modular building and facilitating its domestic development greatly.
