When it comes to architectural design of buildings and homes, the concept of side doors is hugely important. With myriad styles and designs available, there are a variety of synonyms that can be used for side doors. For instance, the term "side entrance" is often used to describe doors that lead to a space adjacent to the main or frontal entrance. "Side access" is another commonly used term that emphasizes the practical positioning of a door that can be accessed without having to traverse the length of an entire building or structure. Other options include "secondary door," "convenience door," and "auxiliary entrance," all of which serve to emphasize the supplementary, easy-to-use nature of doors on a building's side.
