Main issues, as the Inspector framed them
- Whether the Council's decision to refuse to grant a certificate of lawful use or development was well-founded
What decided it
The physical and functional relationship between the outbuilding and main house, including their attachment, shared access arrangements, shared terrace, and common ownership, demonstrated that the proposal would create a residential annexe as part and parcel of the existing dwelling rather than a separate planning unit.
