Frequently Asked Questions

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.

How is the original house defined for measurement purposes?

The “original house” refers to the property as it stood on 1 July 1948 or when it was first built, not including later extensions.

Can I amend my plans after submission?

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

Can I add a balcony to my extension?

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

How close can I build to my neighbour’s boundary?

Extensions built close to a boundary must meet height and eaves restrictions, especially if within two metres of the boundary.

Does building regulations approval still apply?

Yes. Even if planning permission is not required, building regulations approval is usually still necessary.
