[Lost in Cornwall]

A Grade 2 listed building has to have the outside maintained in its original state and can only be changed inside with permission. I have some responsibility as a trustee for a Grade 2 building that was badly damaged by fire 4 years ago and we currently have permission to bring the inside up to modern day standards providing we put the external structure back as close to the original as we can. We are still jumping through hoops to allow that to happen though. Grade 2 star and Grade 1 are virtually impossible to alter at all.
