finished basement

Converted underground space

A finished basement is a below-ground level of a house that has been converted into usable living space—with drywall, flooring, lighting, and climate control rather than exposed concrete and pipes.

The term distinguishes it from an unfinished basement used mainly for storage or utilities: They turned the finished basement into a home theater.

Real estate listings treat finished basements as added square footage.
