The term "Michigan basement" is variously applied to what, in other parts of the country, is often referred to as a "cellar." It can be part of the original construction of a house or it can be an area dug beneath a house that was originaly built over a crawl space. The floor may be dirt or concrete and the walls may be exposed soil, masonry brick or block, or poured concrete. A Michigan basement has a lower ceiling height than a basement and is not considered as habitable space, i.e., space to be used for living, sleeping, dining, etc. Rather, they are commonly used for storage and, in some instances, for laundry equipment.
