Why the need for a big debate?
The site has been listed by WAG.
The site has a covenant, which says it can only be used for educational purposes
The area needs a new school.
As has been said, an imaginative architect will come up with plans to meet all the criteria. An imaginative lawyer will also come up with a definition to suit an interpretation of the covenant. So some kind of museum or arts establishment could be deemed “educational”.
Instead of fighting the “listing” why don’t WCBC go back to the WAG to ask for funding to develop a new school on the site, on the basis they have to use the existing building at the say so of WAG.
Every body wins!
