Before you rely on any of this

1. Flats and maisonettes have none of these rights: houses only.
2. Listed buildings lose most of them, and works to the building itself need Listed Building Consent.
3. Conservation areas and the Cornwall National Landscape (much of our coastline) cut the rights back sharply.
4. Article 4 directions and planning conditions can remove rights street by street or house by house. Common on newer estates.
5. Permitted development is not Building Regulations. You may still need Building Control approval.
