Works that can be carried out without planning permission, are called 'permitted development rights', and include:
- Alterations and maintenance to a building
- certain minor works, including small extensions to houses.
For more details on permitted development rights, visit the Planning Portal.

Conversion of Non-Domestic Buildings into Homes
- Under Permitted Development, existing buildings – such as offices, barns and other agricultural buildings – can be converted into homes.
Agricultural Buildings and Barn Conversions
- The introduction of a new system allows for the conversion of barns into dwellings. Permission would still be required however.
Former Office Buildings
- Another change in ‘permitted development’ allows for offices to be converted to residential use in an attempt to release inner-city land for housing
Permitted development allows for some works to be carried out without planning permission.
In some parts of the country permitted development rights are more restricted:
- Conservation Area
- a National Park
- an Area of Outstanding Natural Beauty
- a World Heritage Site or
- the Norfolk or Suffolk Broads

Unauthorised worksIf you build something which needs planning permission without obtaining permission first, you may be forced to make changes later. This could prove to be very costly and may even result in legal action to require removal of the unauthorised works.
