Thanks. Sorry, no build pictures available. There are four boards total: two, 24" x 24" (Green) and two, 12" x 24" (Red) The walls are glued down, but the grids match up, allowing the boards to be configured in various orientations.
Many of the resin pieces, such as large fan vents, some computer terminals, First-aid stations, power terminals, are glued to the walls permanently. A lot of the details are on plexiglass bases that can be placed per scenario.
I consider it an ongoing project and am currently looking for ways to jazz up the floors.
