Planning and building control

Do I need planning permission?

You may need planning permission before starting work on your property or land. It depends on the type and scale of the work.

When you are likely to need permission

You are more likely to need planning permission if you:

  • build something new
  • make a major change to a building, for example an extension
  • change how a building or land is used

When you may not need permission

You may also need other consents to carry out work. This could include:
