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.

Can I extend a semi-detached house differently to a detached house?

Yes, size limits and projection distances differ depending on property type.

Can I extend a house that has already been extended?

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

What measurements are used for height?

Height is typically measured from the highest ground level adjacent to the building.

Can I convert my garage into living space?

Garage conversions are often permitted development, but planning restrictions may apply depending on conditions attached to the original approval.

Can I extend a flat under permitted development?

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