Main issues, as the Inspector framed them
- The effect of the change of use of the outbuilding on the character and appearance of the area with regard to a mature tree subject to a Tree Preservation Order (TPO)
- Whether the proposed residential annex is in a suitable form and location having regard to development plan policy
What decided it
The outbuilding, whilst free-standing, would function as an ancillary residential annexe to the host dwelling rather than an independent dwelling, and the protected tree would not be at significantly increased risk of harm from the change of use.
