Super simple construction. Just four pieces of foamcore, corrugated plasticard for the roof, and some plasticard for the doors. I threw some junk and assorted doodads around to make them looked lived in. (Eureka 15mm Sci Fi German for scale.) I textured the walls with some light weight putty and they've since been sanded a little. The bases are all destroyed CDs and DVDs, one small benefit of working at a library.
I'm going to be trying some new weathering techniques on these little shanties. I've been reading about using pastels and think these are a perfect place to start. I really want them rundown and sad looking. All those poor settlers have to live somewhere, after all.
