“Any structure designed or adopted for human habitation which is capable of being moved from one place to another (whether by being towed, or by being transported on a motor vehicle so designed or adapted does not include:
- any railway, rolling stock which is for the time being transported on a motor vehicle or trailor and
- any tent.”
The definition was further clarified by the Caravan Sites Act 1968 which defines the detail of a twin caravan:
“A structure designed or adapted for human habitation which: is composed of not more than two sections separately constructed and designed to be assembled on a site by means of bolts, clamps or other devices; and when assembled, physically capable or being towed by road from one place to another (whether by being towed, or by being transported on a motor vehicle or trailer).”
Town and Country Planning SI. 2006 No.2374 amends the definition of the caravan within the Social Landlords (Permissible Additional Purposes) (England) Order 2006 (meaning of caravan) and the Caravan Sites Act 1968. It states that dimensions must not exceed 20m in length, 6.8m in width or exceed a maximum internal height of 3.05m.
