Volume between the floors of a building or between its floor and roof. Storeys are defined as basement (wholly or partly underground), ground (in the USA first and in France rez-de-chaussée), first (or piano nobile if containing the principal rooms), second, third, etc., then Attic (over the entablature of the principal façade). The volume within a roof-space is the garret rather than the Attic. Entresols and mezzanines are intermediate floors between the main storeys. Towers have stages rather than storeys, and, like storeys, are often identified by horizontal bands of mouldings, string-courses, cornices, etc. Storey-posts are the main posts in a timber-framed building, rising one storey.
