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

Can I add bi-fold doors to my extension?

Yes, provided the extension itself complies with permitted development rules and glazing requirements meet building regulations standards.

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.

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