What a grant of permission means
The process from here
Permission has been granted, usually subject to conditions listed on the decision notice, some of which must be discharged before work starts. The decision notice on the council portal sets out exactly what was approved.
Work must normally begin within three years of the decision or the permission lapses. Neighbours cannot appeal a grant; challenging one means judicial review of how the decision was made, within tight time limits.
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.

PA25/00943/PREAPP Decided
Trewan Hall Trewan St Columb Cornwall TR9 6DB
Pre application advice to undertake remedial works to improve structural stability and lateral restraint of the southeast gable end which is bulging outwards at first floor level and has significant external and internal cracking. Proposed works include strengthening existing timber joist with the introduction of steel angles,and threaded rods to tie the new structure to the existing walls and provide lateral restraint. Previous historical repairs, with lower intervention have failed to provide a long term solution and we believe the above proposed solution is the most sensitive and practical approach to secure the future structural stability of the gable end
