Summary
A bungalow extension with an extended gable ridge in a Worthing cul-de-sac, appealed for non-determination. Dismissed. The extra bulk above ground-floor level would overshadow the neighbour's only dining-room window, conflicting with DM5 and Framework P3. Under S4, the personal benefits were substantially outweighed (DL ¶15). No consultation on the new Framework was needed (DL ¶2).
What made the difference
The harm fell on a single side-facing window that was the room's only window. The permitted development fallback was less harmful, so it carried very limited weight (DL ¶10).
Policy findings
Policy codes are those of the National Planning Policy Framework (August 2026) unless a development plan is named.
| Policy | Finding | Weight | Note |
|---|---|---|---|
| P3 | fail | hip-to-gable ridge extension overshadows and encloses the sole dining-room side window at No 5 (DL 6-9, 15) | |
| S4(1) | fail | personal benefits (space, energy performance) limited; substantially outweighed (DL 14-15) |
Key facts
- Non-determination appeal; permitted development fallback (rear dormer) less harmful, so very limited weight
