Approved document F, Ventilation, suggests that a ‘habitable room’ is:
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.
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.'
