Summary
Conversion and extension of an end-terrace house in Barnet into two flats. Allowed despite a breach of the size thresholds in local policy HOU03(C), because the scheme kept a 3-bed family unit and so met the policy's "overarching aims" (DL ¶9-10). The letter never mentions the Framework. The footer carries a different reference (6006098), which looks like a template slip.
What made the difference
Keeping a family-sized unit, and a second flat that exceeds NDSS, outweighed a numerical conflict with the plan (DL ¶18: "material considerations indicate that a decision should be made other than in accordance with it"). No Framework policy was engaged. L2(1)(d) (additional homes within existing plots) could have been cited but was not.
Policy findings
Policy codes are those of the National Planning Policy Framework (August 2026) unless a development plan is named.
| Policy | Finding | Weight | Note |
|---|---|---|---|
| HOU03 (Barnet LP) | conflict | criterion C breached (existing GIA under 135 sq m; flat 2 under 61 sq m), but "overarching aims" met because a 3-bed/4-person family unit is retained (DL 7-10) | |
| CHD01 (Barnet LP) | accord | good standard of amenity; flat 2 exceeds NDSS (DL 9-10) | |
| DM6 | neutral | council-requested PD-removal condition not imposed as "overly restrictive" (DL 17); code mapped by harvester |
Key facts
- Existing GIA below the 135 sq m threshold in HOU03(C); flat 2 below the 61 sq m target but above NDSS
- One 3-bed 4-person family flat retained
