Tbh I'm sure some of these people would rather the building authentically fell to ruin than be updated in any way. Their thinking is totally at odds to the world we live in.I have and they are very smart. But they don't look like Kent peg tiles and thus couldn't possibly be installed on or near a period building according to our council nimbys.
Don't get me wrong, when you're the custodian of a listed property you know that things are never straightforward but there are ways to use modern construction and materials and maintain the look, character and huge parts of the original building and make it sympathetic to the style of the property as well.
