Just a quickie to show you what's on here.
The idea here is to build a block-house in stand-alone form that I can drop into a terrain piece. The circular part is an industrial-scale toilet-paper roll cut in half with a saw, whlie the gable-ends and ceiling are of that perennial favourite, foam-core board.
The the roof and all the rest of the "corrugated iron cladding are a roll of finely corrugated cardboard I found a few years back in a stationers. It has a flat backing so it takes an even skim of glue well for when I have to laminate it onto a thicker card for stability. It's just been cut as a square and scored to fold for the roof.
The miniatures are Hinchcliffe in the Slade Wallace personal equipment. Very nice figures that I'd never really considered before.
