The term 'Levels of a Building' can be defined as the storeys of a building. Storeys are the different levels of a building, typically divided by floors. A storey is usually measured from the ground level up to the roof of the building. Storeys are often used to refer to the number of stories in a building, such as a two-storey house or a five-storey apartment building. Storeys are also used to refer to the height of a building, such as a ten-storey skyscraper.
