Home improvement projects should be carefully considered. Time spent planning can save money. It can also ensure work is completed on time and as required. It is the property owner’s responsibility to ensure that the relevant statutory requirements are met. If the development fails to comply with relevant legislation, the owner is liable for any remedial action.
These charts provide guidance to assist you to decide if your development is permitted development for common projects.
Single storey ground floor extension – Class 1A
Ground floor extension of more than one storey – Class 1B
Construction or alteration of a porch – Class 1C
Alteration to a roof – Class 1D
Access ramp – Class 2A
Changes to the appearance of your house which are not an extension – Class 2B
Outbuildings: sheds, sun houses, greenhouses and garages – Class 3A
Other building work – Class 3B
Hard surface: paving, patios and driveways – Class 3C
Decking and raised platforms – Class 3D
Gates, fences and walls – Class 3F (This is in the process of being updated)
Flats – Class 4A
These charts are not definitive and are for guidance only. If in doubt, please contact your planning authority.
With all building work, the owner of the property (or land) in question is ultimately responsible for complying with the relevant planning rules and building regulations.
