Selective demolition is a process of removing specific portions or components of a building or structure while preserving the remaining parts. It involves carefully dismantling or deconstructing certain parts of a structure without damaging or altering the surrounding areas.

Selective demolition is commonly used in renovation or remodeling projects, where only certain parts of a building need to be removed to make way for new construction or to modify the existing structure. It can also be used in situations where a building needs to be partially demolished, such as when a portion of the structure has been damaged or is no longer safe.

The goal of selective demolition is to minimize waste and reduce the environmental impact of demolition by salvaging materials that can be reused or recycled. It requires careful planning and execution to ensure that the remaining structure remains stable and safe for workers and occupants.
