SNPA Article 4

Defined Article 4 Directions in Snowdonia National Park, the limit of each Article 4 Direction is recorded as a polygon. Householders in England and Wales are allowed to make minor changes to their properties without planning permission from the local planning authority - known as 'permitted development rights'. Sometimes these rights need to be removed to protect the character of an area, usually in Conservation Areas. The application of an Article 4 Direction removes these 'permitted development' rights and is a way in which Local Planning Authorities can control building works and changes of use which would ordinarily be 'permitted development'.
