What Needs Planning Permission?
Many domestic works fall under Permitted Development and do not need an application:
- Rear extensions: Up to 3m (attached) or 4m (detached) single storey
- Loft conversions: Up to 40m³ (terrace) or 50m³ (detached/semi)

If in doubt, apply for a Lawful Development Certificate (£129) to confirm your project is permitted development.
