Kellergeschoß

Kellergeschoß is a German term that translates to "basement" or "cellar story" in English. It refers to the lowest floor of a building, typically located below ground level or partially below ground level. Kellergeschosse are a common feature in residential, commercial, and industrial buildings across German-speaking countries and in many other parts of the world.

The construction of a Kellergeschoß involves excavating the ground before the building's foundation is laid, allowing for a subterranean level. These spaces are often used for storage, housing utilities such as heating systems and water tanks, or as parking garages. In residential buildings, a Kellergeschoß can also be used as living space, such as bedrooms, a home office, or a recreational area, though this is less common than in modern constructions. The presence of a Kellergeschoß can provide valuable additional space without increasing the building's footprint above ground.

The term Kellergeschoß is distinct from a cellar, which usually implies a smaller, often unheated space used primarily for storage, particularly of wine or food. While a Kellergeschoß can contain a cellar, it refers to the entire floor level. Moisture protection and ventilation are important considerations in the construction and use of Kellergeschosse due to their underground location.
