Main issues, as the Inspector framed them
- the effect of the development on the character and appearance of the dwelling and area
- the effect of the development on the living conditions of the occupiers of numbers 25 and 29 Blenheim Road
What decided it
The design refinements to the extension, particularly the set-in walls, integrated dormer windows, and use of matching materials, successfully addressed the concerns that led to dismissal of the previous appeal scheme, ensuring the development would not harm character and appearance or adversely affect neighbouring living conditions.
