Stephen Levrant : Heritage Architecture
133. Where a proposed development will lead to
substantial harm to or total loss
of significance of a designated heritage asset, local planning authorities
should refuse consent, unless it can be demonstrated that the substantial
harm or loss is necessary to achieve
substantial public benefits
that outweigh
that harm or loss,
or
all of the following apply:
.
the nature of the heritage asset prevents all reasonable uses of the site;
and
.
no viable use of the heritage asset itself can be found in the medium term
through appropriate marketing that will enable its conservation; and
.
conservation by grant-funding or some form of charitable or public
ownership is demonstrably not possible; and
.
the harm or loss is outweighed by the benefit of bringing the site back
into use.
