Frequently Asked Questions

Do I need drawings for a Lawful Development Certificate?

Yes. Accurate scaled drawings are required to demonstrate compliance.

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.

Can I extend a flat under permitted development?

Flats and maisonettes generally do not benefit from permitted development rights for extensions.

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 extend a house that has already been extended?

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

Can I appeal a planning refusal?

Yes. Applicants may appeal to the Planning Inspectorate within specified time limits.
