puukerros

Puukerros is a term that appears in Estonian-language discussions related to timber and building, but its exact meaning is not uniform across sources. The phrase can refer to different concepts depending on the context, particularly in architecture, carpentry, and vernacular building descriptions.

In architectural and carpentry contexts, puukerros is sometimes used to denote a wooden floor or a floor system made predominantly of timber. It can describe the structural layer consisting of planks, boards, battens, or other timber components that support flooring. In historical or vernacular descriptions, puukerros may be used to refer to a “wooden storey” or a wooden level within a timber-framed house, as opposed to a brick or stone storey.

In modern practice, more specific terms such as wooden floor, timber floor, board flooring, or engineered timber systems (for example CLT or LVL floors) are more common. Puukerros thus tends to appear primarily in older texts, regional dialects, or in linguistic discussions about Estonian architectural vocabulary.

Etymology and usage notes: The word combines puu (wood) with kerros (layer, floor, tier, storey). Because kerros has multiple related meanings, the precise sense of puukerros depends on the source and on whether the context is architectural description, construction practice, or linguistic analysis.
