Do I need planning permission?

You will need planning permission if you want to alter a building, piece of land or a permanent structure (such as a wall) and you need to carry out building work to do it. You will also need planning permission if your work will change the way the building or land is used.  

You will usually need planning permission to:

• build a new building
• extend or alter an existing building
• make changes to the way a building is used, for example turning a house into flats or making an industrial building into a home
• undertake engineering work or other works, such as sewerage
• demolish a building or structure
• carry out work on a listed building
• carry out work in a conservation area
• carry out work on protected trees or trees in a conservation area
• build new agricultural buildings. 

 

Permitted developments (where you don’t need planning permission)

There are some minor improvements, alterations and extensions you can make to your house that you don’t need planning permission for. These can include construction of some types of porch, glass conservatories under a certain size and also some internal changes.  

Further guidance can be found on the Welsh Government's website.
