Room definition

Approved document B, Fire Safety, Volume 1 Dwelling houses, defines a ‘room’ as:

An enclosed space within a building that is not used solely as a circulation space. The term includes not only conventional rooms, but also cupboards that are not fittings and large spaces such as warehouses and auditoria. The term does not include cavities such as ducts, ceiling cavities and roof spaces.

For more information, see Types of room.
