Yeah, it’s doable if you keep it simple. Use a lightweight frame that sits just behind the stone, then swap out panels that match the original pattern. It gives you a quick way to change the interior without touching the façade. The trick is sealing the gaps so you don’t lose insulation or let water in, and making the panels thick enough to hold up but thin enough not to shift the historic look. It’ll cost a bit more upfront and need some skilled labor, but once set up you can reconfigure rooms on a whim without a new building permit. So practical, just don’t try to fit a perfect square grid onto a 14th‑century ribbed arch.
