Main issues, as the Inspector framed them
- Whether the Authority's decision to refuse to grant a certificate of lawful use or development was well-founded
What decided it
The requirement for occupants to sleep in a tent and caravans inside the building demonstrated that the building did not afford all facilities required for day-to-day private domestic existence and therefore could not be classified as a dwellinghouse.
