Summary
The inspector allowed a two-flat conversion despite ceiling heights below the London Plan D6 standard. The rooms still felt spacious, were dual aspect and would not overheat, so the policy's aims were met (DL 6-9). The Framework is not cited.
What made the difference
The inspector's own inspection of the rooms and the daylight and overheating evidence showed the purpose of D6 was met despite the numerical shortfall.
Policy findings
Policy codes are those of the National Planning Policy Framework (August 2026) unless a development plan is named.
| Policy | Finding | Weight | Note |
|---|---|---|---|
| London Plan D6 | accord | floor-to-ceiling heights below the 2.5 m standard but meet NDSS 2.3 m; dual aspect and daylight study show the policy's aims are met (DL 5-9) |
Key facts
- Ground and first floors below the London Plan 2.5 m ceiling height but above NDSS 2.3 m (DL 5)
- Earlier appeal on the site (3351024) dismissed; changes to windows and a daylight study distinguished it (DL 8)
