Core Refusal Reason
The dormer window is considered visually dominant and obtrusive due to its scale and design, specifically overhanging the rear wall plate to create a de facto three-storey elevation that fails to harmonise with the host dwelling and established residential character.

- Granting retention would set an undesirable precedent for similar types of unsympathetic development, thereby undermining the proper planning and sustainable development of the area.
