Mr. Paul O'Neill:

The exemptions currently provide for a finish that is consistent with the existing building. It is for those reasons of visual impact that one would want a more consistent finish.

As for the structures themselves, the commercially-available ones come in a variety of finishes. It is prefabricated structures that can be finished in accordance with whatever structures are there. They can be rendered or one can have them in glass. There are options available to the operators or to the retailers to ensure that they can avail of the exemption but if they want to move outside that then, for good reason, that is, for visual impact etc., you would want to assess them in a planning application.
