I did post on DIY but no response so here for traffic. I live in a renovated Georgian schoolhouse. Think quirky (not twee) with sash windows and big thick walls. I've only been here 4 months and am starting to put my stamp on it. It's fairly traditionally decorated. My taste is more modern/industrial. Would I be crazy to put polished concrete floors in a 200yr old house? The base slab under the current floor is concrete already.
