The Local Planning Authority, having due regard to the applicant's fall-back position, considers that the replacement of the existing touring caravan with a timber log cabin would result in a material change and intensification in the use of the site resulting in a more permanent form of development with sewerage and service connections which would be harmful to the character of this undeveloped area of woodland within the National Park. Furthermore the retrospective nature of the application with regard to the intentional unauthorised works to the access track, turning and parking areas has prevented measures being taken to mitigate or limit the harm that would be caused to the character and appearance of the locality. As such the proposal is considered to conflict with Core Policy A of the Core Strategy and Development Policies Document which seek to ensure that the scale of development and level of activity does not have an unacceptable impact on the wider landscape or the quiet enjoyment, peace and tranquillity of the Park.
