Frequently Asked Questions

Does an Article 4 Direction affect my extension plans?

Yes. Article 4 Directions remove certain permitted development rights, meaning planning permission may be required.

What is retrospective planning permission?

Retrospective applications seek approval for work already carried out.

Will neighbours be notified?

Under prior approval procedures or planning applications, neighbours are typically notified.

Can I add a balcony to my extension?

Balconies and raised platforms are not permitted development and usually require planning permission.

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.

Can I amend my plans after submission?

Minor amendments may be accepted during determination, depending on the council.
