Habitable room
Approved document F, Ventilation, suggests that a ‘habitable room’ is:
‘…a room used for dwelling purposes but which is not solely a kitchen, utility room, bathroom, cellar or sanitary accommodation.’
Whereas an ‘occupiable room’ is:
‘…a room in a building other than a dwelling that is occupied by people, such as an office, workroom, classroom or hotel bedroom, but not a bathroom, sanitary accommodation, utility room or rooms or spaces used solely or principally for circulation, building services plant or storage purposes.
Approved document M1, Access to and use of buildings: dwellings, defines a habitable room as:
'A room used, or intended to be used, for dwelling purposes, including a kitchen but not a bathroom or utility room.'
The English Housing Survey Housing Stock Report, 2014-15, prepared by the Department of Communities and Local Government, defines a habitable room as:
'A room in the dwelling that offers ‘living accommodation’. Includes bedrooms, kitchens if there is additional space to provide a dining area large enough to accommodate a table and chairs (typically an area of 2m² in addition to kitchen space). A fully converted room in the loft space is classified as a habitable room even if it can only be reached by a fixed ladder or unsafe staircase.'
The Scottish Building Standards refer to a 'principal habitable room' in relation to the provision of fire detection and fire alarm systems.
They define a principal habitable room as ‘…a frequently used room by the occupants of a dwelling for general daytime living purposes.’
