Summary
A first and roof-level side extension on columns to a first-floor maisonette in a semi-detached pair. Dismissed. It would unbalance the pair and look "awkward and contrived", and it would overbear neighbours' side entrances. The L2(1)(d) substantial weight was not available because the scheme was inconsistent with the street scene, and under S4(1) the benefits were substantially outweighed.
What made the difference
The symmetry of the semi-detached pairs along the Crescent, and the neighbours' front doors facing the flank. A void at ground level did not remove the sense of enclosure from the storeys above.
Policy findings
Policy codes are those of the National Planning Policy Framework (August 2026) unless a development plan is named.
| Policy | Finding | Weight | Note |
|---|---|---|---|
| L2(1)(d) | fail | substantial-weight limb for extra floorspace not met as inconsistent with the street scene (DL 15) | |
| S4(1) | fail | unbalances semi-pair, less than 1 m to boundary; overbearing to neighbours' side doors and landing window 2.4 m away (DL 7-16) |
Key facts
- Extension on three columns at the common boundary; neighbours' front doors on side flanks (DL 6, 11)
- Parties asked to comment on 17 Aug 2026 Framework (DL 2)
