The General Permitted Development Order (GPDO) grants permitted development rights in relation to certain development. Where it applies, no specific planning application is required for permission for proposed development. Generally, the rights are for minor developments which are not likely to cause a material planning impact.
Regulations have been published which amend the GPDO. The amendments came into force on 1 October 2008.
Permitted development rights are already restricted in relation to certain categories of property. Under the new regulations, World Heritage Sites are added to the list of land where a more restricted set of permitted development rights applies ("article 1(5) land").
Permitted development rights for domestic properties are contained in Part 1 of Schedule 2 of the Order. This Part is replaced entirely by the amendment regulations and deals with development such as extensions to houses, porches, pools and changes to the roof and external appearance of dwellings.
The changes are mostly to clarify ambiguous or unclear provisions. However, they also introduce a number of new conditions and restrictions on this type of permitted development.
