Summary
A full-width rear dormer on a prominent corner property in Reading. Dismissed on character grounds under Local Plan CC7 and the SPD. The letter names DP3(1) as "the overriding consideration" (DL ¶8) but does not apply the DP3(3) clear-justification step.
Issues and findings
- Character. "Due to the site’s prominent corner location, the proposed rear dormer extension would appear as an overly-large and incongruous feature in the street scene" (DL ¶6).
- Balance. "As these benefits would mainly be private in nature, they merit little weight in support of the proposed development. On the other hand, the proposed development would not integrate with and enhance its surroundings, contrary to policy DP3(1) of the Framework, which is the overriding consideration in this case" (DL ¶8).
Transferable points
- A DP3(1) conflict can outweigh private householder benefits in a plan-led decision (DL ¶8).
Policy findings
Policy codes are those of the National Planning Policy Framework (August 2026) unless a development plan is named.
| Policy | Finding | Weight | Note |
|---|---|---|---|
| DP3(1) | conflict | large, bulky dormer across almost the whole roof, incongruous on a prominent corner; conflict with DP3(1) called "the overriding consideration"; no DP3(3) or clear-justification step (DL 5-8) |
Key facts
- Dormer set only marginally below the ridge and spans almost the full width of the rear roof, against SPD guidance (DL 5)
- Enlarged accommodation is a mainly private benefit, given little weight (DL 8)
