What decided it
The unduly excessive bulk and poor architectural integration of the extension with the host dwelling's existing character would harm the character and appearance of the host dwelling and surrounding area, conflicting with the development plan.
The benefits to the living conditions of the current occupiers were not persuaded to outweigh the harm to character and appearance identified.
