kjelleren

Kjelleren is the definite form of the Norwegian noun kjeller, meaning basement or cellar. It refers to the part of a building that lies below ground level and is used for storage, utilities, or, in some homes, living space. The term is common in everyday language and architectural descriptions in Norwegian.

In ordinary houses, kjelleren is typically accessed by stairs from the main floor. Features commonly include concrete or stone walls, a lower ceiling height, and limited natural light. Historically, kjellere were used for food storage because the cool, stable temperatures help preserve perishables. Today they serve diverse functions such as laundry rooms, housing heating and mechanical systems, general storage, hobby spaces, wine cellars, or a separate kjellerleilighet (basement apartment).

Etymology and related terms: the Norwegian kjeller is cognate with Danish kælder and Swedish källare, and kjelleren means "the cellar." Regional dialects may use other terms for specific spaces, such as underetasje for a lower storey or boder for storage rooms, but kjelleren remains the standard term for a basement area.

Safety and housing context: basements can be prone to damp, mold, and flooding if not properly waterproofed and ventilated. Norwegian building codes emphasize moisture control, ventilation, insulation, and safe egress. In urban areas, older homes often include a kjeller, while newer constructions may repurpose the space for utility rooms or additional living areas.
