A home addition and a renovation can be considered the same thing, depending on what you choose to do with the additional space. If you want to renovate your kitchen or bathrooms and add more living space with an addition at the same time, it may be appropriate to refer to the combined project as a renovation. In most cases, however, homeowners who add on extra rooms or create new areas for entertaining do not call their project a 'renovation,' but instead choose more specific terms such as 'addition,' 'room addition' or perhaps even more descriptive words like 'family room addition.' In general, when additional space is being added to an existing structure, the project is considered an 'addition' while a 'renovation' and 'remodel' usually refers to updating existing structures and rooms.
