Open spatial planning
Approved document B, Fire Safety, Volume 2, Buildings other than dwellinghouses (2019 edition), defines open spatial planning as:
'The internal arrangement of a building in which more than one storey or level is contained in one undivided volume, e.g. split-level floors. For the purposes of this document there is a distinction between open spatial planning and an atrium space.'
An atrium (plural atria) is: 'A continuous space that passes through one or more structural floors within a building, not necessarily vertically. NOTE: Enclosed lift wells, enclosed escalator wells, building services ducts and stairs are not classified as atria.'
