Frequently Asked Questions

Can I amend my plans after submission?

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

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.

What is the maximum size allowed under permitted development?

Size limits depend on property type and location. Detached houses may have larger rear extensions than terraced homes, subject to height and boundary constraints.

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.
