Great looking buildings that are easy to build. In fact I've made mine from 3mm MDF instead of cardstock and it was still effortless. The layers means you can build 2 or three of these without them looking the same which is very handy for bulking out the terrain on a skirmish table. I've also printed these at 10mm scale and they look great.
