Your property

Confirm your address, check your local planning authority and tell us a little about the house.

Start with your postcode

Enter it at the top of the page and we will find your property and your local planning authority.

We keep this on your order so we can identify your project. It is not checked against an address database.

Permitted Development Rights coverage: our drawings and guidance cover properties in England. Different planning rules apply in Scotland, Wales and Northern Ireland.
Your local planning authority

We will show your council, its planning website and its application search once you enter a postcode.

Check your Permitted Development rights

Before purchasing your drawings, please check the following. This helps us confirm whether your project is likely to benefit from Permitted Development rights.

View full guidance
  • Your property is a house (not a flat or maisonette)
  • Check listed building status
  • Check conservation area or other designated land
  • Check Article 4 directions or planning conditions
  • Check previous extensions or alterations affecting the original house
Required before continuing

I confirm that I have checked my property and believe it benefits from the Permitted Development rights required for the project I am selecting, and understand that it is my responsibility to ensure the selected project is suitable for my property.
