Main issues, as the Inspector framed them

  • The effect of the bathroom installation on the character of its surroundings and neighbouring residential living conditions

What decided it

The strong and clear functional linkages between the outbuilding and the host property, combined with the absence of evidence of actual harm to local residents or character, meant the development could be acceptably used on an ancillary basis to the main dwelling.
