Frequently Asked Questions

Is planning permission needed for internal alterations?

Internal changes usually do not require planning permission unless the property is listed.

Can I build a two-storey extension without planning permission?

Two-storey extensions are sometimes permitted, but stricter limits apply to height, rear projection distance, and window placement to avoid overlooking neighbours.

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 remove a chimney without permission?

External alterations may require permission depending on property type and location.

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.

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.
