I'm in Village d'Artisans and having the same problem. It's supposed to be 18x18, and I have a 20x20 area cleared for it, but the village won't build the estate or the huge plot.
There's a basement to it, so I kind of wonder if maybe there are holes beneath my plot that need to be filled before they'll start construction.
I finished upgrading the Norman village of "Tierceville L'ocean."
I bought the Hotel Particular as an extra building for me, but they won't build it because it's "lacking space."
I've filled in many gaps in the land, some water, and flattened out so much land but still nothing...
Does anyone have this village upgraded with the Hotel particular and can tell me where this house is supposed to be built so I can make room for it?!?
