The buildings come in 5 types: extractors, processors, factory, auxiliary, and warehouses. Exceptions are the warehouses and Unique Factories, as well as the Postal Service buildings. Zoned industry can exist within Industry Areas, but most of the user placed buildings from the Industries DLC need to be within an Industry Area. The two types can both be utilized in the same city. The Industries DLC added the ability to create specialized industrial zones called ' Industry Areas' with user placed buildings, as opposed to the base game's growable buildings in the specialized zoned industry.
Available only with the Industries DLC enabled.
