Paragraph 197 of the NPPF says:
“The effect of an application on the significance of a non-designated heritage asset should be taken into account in determining the application. In weighing applications that directly or indirectly affect non-designated heritage assets, a balanced judgement will be required having regard to the scale of any harm or loss and the significance of the heritage asset.”
What, though, is a non-designated heritage asset? It’s no use turning to the Glossary for help – it’s not there. As is so often the case in planning it is, therefore, a case of building a picture, and an inspector dealing with an appeal against the refusal of permission for four houses in south London has helped with the work (DCS Number 200-007-876).
The inspector noted that the site was not in a conservation area (and thus was not a designated heritage asset), but it was proposed to be. Having regard to the evidence set out in the conservation area appraisal he was satisfied that the area was of some historical significance. Thus, he declared “it is of sufficient interest to be considered in this appeal as a non-designated heritage asset.”
The inspector judged that the design of the properties was not intrinsically poor but held that it would not integrate suitably with its context. Consequently, he found that the development would appear as an overbearing and discordant feature to the detriment of the street scene and the significance of the non-designated heritage asset.
Section 4.3736 of DCP Online addresses the topic of emerging conservation areas.
