This is the leftover frame for some boardgame pieces. It looks a lot like window frames or breezeway arches. I'm going to go with breezeways.
They will need end bits to hold them together and hold up the roof.
This is a pretty simple structure.
And a standard corrugated cardboard roof. I am mixing several colours of paint right on the surface. This gives a nice water run/weathered effect.
Then we just stand them up and let the space marines run around.
The one in front has a slightly more interesting structure because I had one frame bit with "two stories".
