Most were made from extruded polystyrene insulation board cut into slabs of various thicknesses. The walls are cut to size and glued together with artist's matte medium. Straight pins are used to hold the walls in place while the matte medium dries. They are mounted on .06" styrene plastic sheet.
That's Kayly helping out in the last two pics. She is quite the dust collector, when I'm working with the foam.
After construction, the buildings were given a coat of acrylic paste and painted with artist's acrylics.
Some of the buildings were constructed in both pre and post battle condition.
The last building is a border security station made from sheet styrene and using GrandtLine styrene windows.
That's it for now, I'll be adding more soon.
