- **Decision:** allowed, 26 August 2026

- **Authority:** Barnet (London)
- **Appeal reference:** 6003738

## 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
- **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)
