Historical Associations as Listing Criteria
Buildings with historical associations require additional quality or interest in their physical fabric to justify listing, either through architectural merit or preservation of features that reveal their historical significance.
In the case of historical associations, there will generally need to be some additional quality or interest in the physical fabric of the building itself to justify listing. Either the building will have architectural merit in itself or it should be well preserved in a form which directly reveals its historical associations (e.g. because of the survival of certain particular features).
