What happens at appeal
The process from here
This application is at appeal, which passes the decision from the council to the national planning inspectorate, or in Scotland usually to a local review body first. The appeal considers the scheme afresh against the same policies.
Anyone who commented on the original application is normally notified and can comment again within the appeal deadline. Appeal decisions take months rather than weeks, and the outcome replaces the council's decision.
About heritage and listed buildings applications
How this application type works
Heritage applications concern listed buildings and conservation areas. Listed building consent is needed for works, inside or out, that affect the special interest of a listed building, and carrying out such works without consent is a criminal offence. The council weighs harm to the heritage asset against any public benefit of the proposal.
