If your building project requires planning permission, you submit a planning application which explains your building project in detail including things like the size, height, location and materials that will be used.
This helps us make a decision on whether your building project is acceptable.
You can apply for planning permission even if you don't own the property yet.

If you start a project without the required permission, we may ask you to make a retrospective planning application.
We'll give you permission as long as what you've built would have been acceptable from the start.
However, if we decide that permission shouldn't have been granted you'll need to put things back as they were at your own cost or we'll take enforcement action.
There are various types of application forms and it's important to submit the right one otherwise this could delay your building project.
Used for projects that alter or enlarge a single house, including works within the boundary/garden of a house.

Once outline planning permission has been approved, you will need to apply for “reserved matters”. What's this?

These details need to be submitted for approval before the project can progress. These sometimes have to be submitted at a set time, either before works start or before the new development can be used/occupied. Please read any conditions carefully.
Some building projects involving larger household extensions, some changes of use, telecommunications, demolition, agriculture or forestry are subject to a process whereby details are notified to the local planning authority prior to the development taking place.
