The restoration architect who owns the fortified farmhouse at Chateau du Sailhant could help. One of the things he did was visit every one of the 40 chateaux open to the public in his area to survey all those issues for local "appropriate" solutions.
He has a lot of wallpaper, which obviously cannot adhere unless the rising damp and buried live wire issues are dealt with.

As for "appropriate" even people of expertise, good will, and good taste, like the Sailhant guy, have a case that a fortified farmhouse is posh, always was, has been since the 10th century, but yet does not need to be "restored" to only one of the eras in which it has existed.
The one paint sample we have for Lalande is the ox-blood painted beams Ian uncovered, with rustic white flowers painted on them. For which we're still awaiting radio carbon dating or whatever she promised she was going to do.
I wouldn't live in a house that color. Though I have a lot of ideas about how to decorate the fortified farmhouse based on that artifact. Posh, fresh, rustic -- in the traditions as Tartlets have suggested of Fowler and Colefax, Sister Parrish -- posh country house tradition which has its own kind of Marie Antoinette the milkmaid tradition in France. Sailhant's wallpapers are very different from Jarvis' -- he has a faux stone one, very handsome, and a stylized starburst one, ditto.
I get the same feeling from Sailhant as I did from Marc's tour of his family house -- not Rosieres -- of a more masculine pre-Baroque Renaissance style. With plenty of telescopes, globes, microscopes, bug collections, cabinets of curiousities. And war trophies. (I don't like Chenonceau's furnishings any better, but at least they're not Louis Farouk.)
Have a look at the professional restoration architect's restoration of the fortified farmhouse at Chateau du Sailhant.
It's posh.
Also not my taste.
Fanny has successfully been talked down from the Versailles ledge by Davy in terms of the garden, where he persuaded her that Chenonceau Renaissance parterres were more sustainable and design-appropriate.
But Pheeph, whose intentions are imperialistic, can't be counted on to make the same argument for "appropriateness" -- or sustainability.
I think that would be an argument for sustainability, posh, for Renaissance, Chenonceau, not Baroque, of which the architecture of Versailles itself was apparently the show piece.
Judging from Sailhant and Chenonceau, the problem with Renaissance posh is that none of the furniture looks like a human being could sit on it. Or lounge on it, as we now all do.
Finally, Jarvis thinks she is an expert and has the flair for this, even though on our watch she has literally fucked up every project she has attempted. I'll never forget the lecture
@MarquisOfNadaillac gave on the sequence of wallpaper panels after she messed up the loo wallpaper. Clearly, messing that up triggers outrage in the expert interior design world the same way Jarvis' violation of hospitality and food values sets me on fire. She's pissing away those wallpapers the same way she pisses away black currants and lakes and ponds.
What's inappropriate, we can all agree is tall Baroque panelling in that low-ceilinged Renaissance room. Without heating infrastructure. Another fuckup.
