Frequently Asked Questions

Are side extensions allowed under permitted development?

Side extensions are permitted in some cases, but must not exceed half the width of the original house and must meet height limits.

What is the difference between planning permission and building regulations?

Planning permission controls development impact, while building regulations ensure structural safety and compliance.

Can I amend my plans after submission?

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

Does my extension need to match existing materials?

While not always mandatory under permitted development, matching materials is often recommended for visual consistency.

What happens if I build without permission?

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

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.
