Frequently Asked Questions

Are basements covered by permitted development?

Basement development may require planning permission, especially if it alters the external appearance.

What happens if permitted development rights have been removed?

If rights have been removed by planning condition or Article 4 Direction, you will likely need to submit a full planning application before building.

What is a Lawful Development Certificate?

A Lawful Development Certificate provides formal confirmation from the local authority that your extension complies with permitted development rules.

Do conservation areas affect permitted development rights?

Yes. Properties within conservation areas often have additional restrictions, and some permitted development rights may be limited or removed entirely.

What is the 45-degree rule?

The 45-degree rule is a guideline used by some councils to assess impact on neighbouring properties, particularly in relation to light and outlook.

Can I extend a flat under permitted development?

Flats and maisonettes generally do not benefit from permitted development rights for extensions.
