模块化夹层是一种方便且具有成本效益的方法，可以快速在现有大型结构的内部（例如仓库，零售商店）中创建额外的地板空间或工业大楼。  Popular designs include structural framing, stairs, and steel grate decking.  The most common purpose of modular mezzanines is to provide additional storage space.  Some specialized modular mezzanines provide enclosed rooms with complete utility services, including lighting and air conditioning, to create offices and finished interior spaces.
