Which of the following best describes the term "Rehabilitation" in design?

The term "Rehabilitation" in design refers to a process that allows for the repair and modification of existing structures while still respecting their historical significance. It acknowledges that while some original materials and features may need to be preserved, it is sometimes necessary and appropriate to replace materials that have deteriorated or are no longer functional. This balance allows structures to be updated and made suitable for current use, while still maintaining their essential character and heritage.

By focusing on repair—with potential material replacement—rehabilitation aims to extend the lifespan of a structure and adapt it for contemporary use. This approach is often employed in the context of historic preservation where the goal is not just to freeze a building in time, but to ensure its relevance and functionality in today's environment.
