Planning permission or permitted development?
In England many householder projects can be built under permitted development (PD) rights without applying for planning permission. PD rights can be removed by an Article 4 direction, and are restricted in conservation areas, national parks and for listed buildings.
Wales, Scotland and Northern Ireland have their own versions, so always check your nation's rules.
Key terms
- Curtilage – the land around your house.
- Principal elevation – usually the front facing the road; extensions in front of it need permission.
- Lawful Development Certificate – written proof that your project is PD.
- Prior approval – a light-touch procedure for larger rear extensions.
Frequently asked questions
Do I need a Lawful Development Certificate?
It is optional but recommended, as it proves the work was lawful when you sell the house.
Rules change and are applied locally. Always check with your local planning authority and Building Control before you build.
