The site is not considered to form a small infill gap within a continuously built up frontage in the main built up area of Sleights, and consequently constitutes housing development in the open countryside for which there is no proven essential need. If permitted the proposal would consolidate this pocket of sporadic development in the countryside and would give the locality a much more built up, urban appearance which would be harmful to the character and appearance of the landscape of this part of the National Park. As such the proposal is contrary to Core Policies A and J of the Core Strategy and Development Policies Document and the National Planning Policy Framework which seek to confine new housing development to the main built up areas of the settlements of the National Park and restrict new housing in the open countryside unless there are special circumstances. No such circumstances exist in this case.
