Summary
An attached new dwelling on the Becontree Estate, a non-designated heritage asset, was dismissed. It caused significant harm to the uniform terrace and was served by unlawful footway-crossing parking. An extant extension permission counted as a moderate-weight fallback but was less harmful. The Framework is mentioned only in passing and no version is given. The L2(1)(d) "additional units within residential curtilages" test was not engaged.
What made the difference
The single-storey side infill up to the boundary and the second front door made the scheme read as a narrow separate house, which did more harm than the fallback (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 |
|---|---|---|---|
| HE7(2) | harm | "significant harm" to Becontree Estate NDHA; unsubordinate, narrow frontage unbalances the terrace, garden subdivided (DL 3-12); HE7 not named | |
| TR4(1)(c)(i) | fail | Framework not cited; cars would cross footway unlawfully (no dropped kerb, CPZ bay) (DL 14-18) |
Key facts
- Extant householder permission for similar two-storey side extension, fallback given moderate weight (DL 8-9)
- Offer to go car-free not accompanied by plans; not for appeal to evolve schemes (DL 17)
