No one mentioned appealing the listing. You can, according to DCSM advice apply to de- list a building and the stronger the community voice and rationale, the better.

A decision to list a building is taken solely on grounds of architectural or historic interest. There is no formal right of appeal against this decision, at the moment of listing, but an owner may at any time put to the Secretary of State evidence that his building does not possess the architectural or historic interest identified. If the Secretary of State accepts that the original assessment of a building's interest was wrong in this way, and that it does not possess special interest, he will then 'de-list' the building.
