Frequently Asked Questions

Can I extend a house that has already been extended?

Permitted development limits are cumulative, so previous extensions may reduce what is still allowed.

Can I convert my garage into living space?

Garage conversions are often permitted development, but planning restrictions may apply depending on conditions attached to the original approval.

Does an Article 4 Direction affect my extension plans?

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

Can I extend in a National Park?

National Parks have stricter controls and reduced permitted development rights.

Do I need prior approval for a larger extension?

In some cases, larger home extensions require a prior approval process where neighbours are notified and the council assesses certain impacts.

What happens if I build without permission?

The council may take enforcement action requiring alterations or removal of unauthorised works.
