## Summary
A retrospective variation to keep an as-built front boundary treatment on a prominent Birkdale corner was dismissed. It caused significant harm to the area's open character of low brick walls and gardens (DL ¶14).

## What made the difference
The prominent corner and the consistent local boundary pattern. The inspector ran the S4 test even for a boundary treatment, finding the harm substantially outweighed "the benefit afforded to development within a settlement" (DL ¶17).

## Policy findings
- **DP3: fail (significant weight).** retained boundary treatment harms an open, verdant corner characterised by low red-brick walls (DL 7-14)
- **S4: fail.** adverse effects "substantially outweigh the benefits … including the benefit afforded to development within a settlement" (DL 17)

## Key facts
- Not re-consulted: "no substantive changes in the new Framework relevant to this appeal" (DL 2)
