The combined effect of the enlarged dormer form and the introduction of an inappropriate and visually discordant material would fail to respect the design rationale of the approved scheme and would be harmful to the established character and appearance of the host building and the wider street scene. Furthermore, the proposal would set an undesirable precedent for similar roof alterations within the locality, which, if repeated, would lead to cumulative harm to the visual coherence and architectural integrity of the area. The development is therefore contrary to London Plan Policy D3 and Havering Local Plan Policies 7 and 26. |
