Poster Panels in Predominantly Commercial Areas
Poster panel displays may be acceptable in commercial areas where building scale is sufficiently large, provided the advertisement scale respects adjacent buildings and the wider area character.
In commercial areas the scale of buildings may be sufficiently large to accommodate poster panel displays without adverse effect on visual amenity. The scale of commercial and industrial surroundings in our cities and towns can however vary greatly, often within short distances. It will be expected therefore that the scale of advertisement displays should respect the scale of adjacent buildings and the wider area.
