In additional to the National mandatory documents you are also required to submit the following:
- 2 copies of existing and proposed elevations to a metric scale of 1:50 or 1:100.
- 2 copies of existing and proposed floor plans to a metric scale of 1:50 or 1:100.
- 2 copies of photographs showing the existing details and 2 copies of a photomontage showing the proposed effect.
- 2 copies of plans showing key architectural details to a metric scale of 1:20. This may include any new windows, doors and gates.
- 2 copies of existing and proposed sections to a metric scale of 1:50 or 1:100.
- 2 copies of a Heritage Statement.
The National Planning Policy Framework requires an applicant to describe the significance of any heritage assets affected. This includes any contribution made by their setting.
The level of detail should:
- be relative to the importance of the assets,
- be enough to understand the potential impact of the proposal on the significance of the assets, and
- provide a clear justification (rationale) for the proposal.
As a minimum the Council’s historic environment record should have been consulted and the heritage assets assessed using appropriate expertise where necessary.
Where an application site has potential for archaeological interest a desk-based assessment would normally suffice but in some situations a field evaluation would be required.
