Have my Permitted Development rights been removed?
Permitted development rights may have been removed by a condition on a previous planning consent (dating back to 1948) or by an Article 4 direction. In order to find out whether such condition exists, the property history will need to be thoroughly investigated. More information about how to search planning history for a site can be found here. Article 4 Directions and the properties they relate to can be found here.
