Päätasolla

Päätasolla is a Finnish adverbial form meaning on the main level or on the principal floor. It is formed from pää- (main, principal) and taso (level, floor) with the locative suffix -lla, indicating location. The term is primarily used in architectural, construction, and real estate contexts to describe the position of spaces within a building.

In practice, päätasolla refers to the level considered central or primary in a given plan. The exact interpretation of whether this corresponds to the ground floor, the first floor, or another storey depends on local architectural conventions and the design of the building. The term is most common in technical descriptions, drawings, and property listings, where precise floor location is important.

Because päätasolla is a domain-specific expression, it is typically used in professional contexts rather than everyday conversation. To avoid ambiguity, it is often accompanied by more explicit terms such as pohjakerros (ground floor), ensimmäinen kerros (first floor), or kerros (storey). Etymologically, the word exemplifies Finnish compounding patterns and its role in specialized vocabulary for architecture and real estate. See also related terms: taso, kerros, pohjakerros.
