Other uses for these and other types of portable buildings are as guard shacks, in-plant offices (these are typically portable steel buildings), rural offices, on-site changing rooms, etc. Some portable buildings can be made very complex by joining units and forming large office blocks over several floors. These are often disguised as a normal building with brick style cladding and a traditional pitched roof.

In Australia, small portable dwellings are often called dongas. In Australia the word "demountable" in particular refers to portable classrooms. In the United Kingdom the words "Portakabin", "Portacabin", "Bunkabin" and "terrapin" are commonly used to describe these buildings. The use of these words as generic descriptions of portable buildings has caused contention amongst some manufacturers. The "Portakabin" spelling with a 'k' is a trademark owned by Portakabin Ltd to identify its range of relocatable and modular buildings but is often used as a generic trademark to mean any portable building of that general pattern. The spelling with a 'c' normally refers to similar temporary buildings made by other companies; Portakabin Ltd argues that the spelling "portacabin" is a misspelling. "Terrapin" like Portakabin, is a portable building manufacturer, although the term "terrapin building" is often used to describe any modular or prefabricated building. The use of “terrapin” dates back further than “Portakabin or “Portacabin” as the company has been trading for over 60 years. The phrase “terrapin classroom” arose from the sudden need for additional classroom space following the post-World War II baby boom era, and is now common usage for any portable classroom. In Canada, Australia, and elsewhere, portable buildings are sometimes referred to as "ATCO huts," after the Canadian energy company that manufactures a line of them in one of its business units. ==See also==
