These are beautiful!
I know it's been a couple of years since you made these (and I'm sure I could figure out how to do it myself eventually), but I was wondering if you'd mind either adding window props (that don't have the stucco surround), or add windows with stone surrounds?
Note I'm playing with Asset Forge scripting to create houses automatically. The capabilities are quite a bit more limited than Godot's mentioned in an earlier comment, but it'll be nice to have something as a starting point either way. I've almost got it to the stage that Daniel Dewael had in his screenshot. FWIW, I'll be sure to share when I'm a bit further along.
