Step-by-step explanation:
The practice described in the question is referred to as adaptive reuse in architecture. This involves redesigning and using a structure for a purpose that is significantly different from its original use. Adaptive reuse is a sustainable approach to architecture as it reduces the need for new construction and preserves historic structures.
For example, an old factory building might be transformed into a modern office space or an abandoned church might be converted into a community center. Adaptive reuse allows architects to repurpose existing structures, taking advantage of their unique features and history.
This practice is especially important in urban areas where there may be limited available land for new construction. It allows architects to make the most of existing structures, creating functional spaces that meet the needs of the community.
