I really don't know what would be best (or even 'usual' in this situation) - all I can say is that the solutions being discussed (even if compliant) do not sound at all 'nice' to me. I've never had to deal with walls with metal inside them, and that's why I would seek the assistance of someone who did have experience of such situations if I ever had such a need - and that's even in my own domestic situation. Add that to all the legal, insurance, lease etc. issues in a commercial property and I wouldn't personally touch it with a bargepole!Hi John, What would be the best compliant way of doing this??
However, all any of us can do is offer our person opinions - only you can decide how you want to play it.
Kind Regards, John
