Summary
A replacement four-bed house in Harpenden was allowed after the council failed to decide it within the statutory period. The inspector found no harm to the outlook of the neighbouring house because of the proposal's setback and low-eaves side profile (DL ¶9-10). The decision cites Framework P3 on noise and light (DL ¶16), and DM6 on conditions (DL ¶18).
What made the difference
The deepest projection is single-storey and the roof slopes away from No 46, whose main outlook is down its own garden (DL ¶9-10). The self-build BNG exemption survived because the application was made before 6 Aug 2026 (DL ¶22).
Policy findings
Policy codes are those of the National Planning Policy Framework (August 2026) unless a development plan is named.
| Policy | Finding | Weight | Note |
|---|---|---|---|
| P3 | pass | no harmful overbearing, privacy or light-pollution effect on No 46 (DL 8-16) | |
| DM6 | accord | pre-commencement conditions avoided unless clearly justified; construction management plan justified; PD-removal condition refused per PPG (DL 18-26) |
Key facts
- Adjacent to Harpenden Conservation Area; no harm to its setting (DL 4)
- Framework: "no material differences" from the superseded version on this issue (DL 5)
- BNG self-build exemption still applied because the application predated 6 Aug 2026; self-build condition imposed (DL 22)
