…barring basing, which I need a bit of a think about, as I now have a cluster of buildings (the Mansio and its outbuildings, plus the Warbases ruined villa and outbuilding) that I’m debating whether to base as one group or two.

Wall texture is PVA + ballast as before. Definitely (for those who followed the interactions with Warbases on Twitter) easier with the instructions, although I would recommend when it comes to putting the four walls and base together, using something that sets faster than PVA 😀
