The appellant noted that the council, in granting permission, had not imposed a condition limiting the number of caravans. On that basis, he asserted that increasing the number to 12 would not trigger a material change of use. The inspector agreed that the judgement in Childs v First Secretary of State and Test Valley Borough Council  established the principle that an increase in the number of caravans on a site may be capable of constituting a material change of use.
This must be a matter of fact and degree, he concluded. He noted that the appeal site was well screened and decided that an increase in the number of caravans would not adversely affect the area's character and appearance. An associated increase in the number of vehicular movements would not materially affect local roads, he held.
