Summary
Subdividing an upper flat in Acton with dormered roof accommodation was dismissed. The dormers cluttered the roofscape, and NDSS headroom for the new roof flat was not shown. Under S4 the limited benefit of one unit, with "no specific housing shortfall" advised, was substantially outweighed (DL ¶13-14).
What made the difference
Without shortfall evidence, the APO treated efficient use of land as the baseline, not a benefit: "an efficient use of land would be expected to make a proposal acceptable in principle" (DL ¶13). The letter refers to the old NPPF's "section 12".
Policy findings
Policy codes are those of the National Planning Policy Framework (August 2026) unless a development plan is named.
| Policy | Finding | Weight | Note |
|---|---|---|---|
| S4 | fail | one unit, no specific shortfall advised - limited weight; enduring design and NDSS headroom harm significant weight - substantially outweighed (DL 13-14) |
Key facts
- Catslide dormers on outrigger clutter plain terrace roofscape; unproven 2.2 m headroom over 75% of the roof flat
- No re-consultation on the new Framework; "section 12" reference to the old NPPF chapter numbering (DL 14)
