What refusal means
The process from here
The council refused this application for the reasons set out on the decision notice, which the council portal holds in full. Only the applicant can appeal a refusal; the time limit runs from the decision date and is shorter for householder schemes.
Refusal does not prevent a fresh attempt. Applicants often address the reasons for refusal and resubmit, so a refused scheme is not necessarily the end of proposals for the site.
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.
