Main issues, as the Inspector framed them
- Whether the proposal would preserve or enhance the character or appearance of the St Albans Conservation Area
What decided it
The form, mass and design of the proposal would appear discordant within its immediate context on Victoria Street and would not preserve or enhance the character and appearance of the conservation area, and the public benefits do not outweigh this less than substantial harm.
What the Inspector cited
- Development plan policies
- Saved Policy 69 (General Design and Layout)Saved Policy 70 (Design and Layout of New Housing)Saved Policy 85 (Development in Conservation Areas)
How the Inspector dealt with each one is set out in the app, in order: the development plan, national policy, housing land supply, other considerations and the planning balance, beside the letter.
