Storeys of a building

The British English word ‘storey’ (plural storeys) and the American English ‘story’ (plural stories) refer to a level element of a building that has a useable floor. The term may be used interchangeably with ‘floor’, ‘level’, or ‘deck’; however, it is usual for a building to be described as a ’ten-storey building’ while the individual storey may be referred to as the ‘tenth floor’.

Storey’ tends to exclude building levels that are not covered by a roof, such as a roof terrace. It is also not used to refer to the street level floor which is typically called the ‘ground floor’.

Most houses are two-storeys, while bungalows are single-storey. A multi-storey building is a building that has multiple storeys, and typically contains vertical circulation in the form of ramps, stairs and lifts.

Buildings can be classified by the number of storeys they have.

Storey heights tend to be based on the ceiling height of the rooms in addition to the floor thickness. They are commonly 3 to 4.5 m, but can vary significantly depending on the room type. Storey heights can also vary throughout a building.
