Questions about planning in South Downs National Park
Do I need planning permission for my project in South Downs National Park?
Some house extensions, loft conversions and outbuildings can use permitted development rights in South Downs National Park, but size alone does not establish eligibility. Check the property type, previous extensions, planning conditions and the rules for the proposed work. Householder rights do not apply to flats. Conservation areas and Article 4 directions restrict particular rights; they do not automatically require an application for every change. Listed building consent is a separate requirement for works affecting a listed building's special interest.
