These photos are very much a work in progress, it is far from finished and I need to tweak quite lot, but I have the basic design pretty much sorted out now...
I designed the system so that it can be used with Fenris Games Sulaco Corridor tiles. In these photos though, I have used 6mm MDF for the floors, as that is what the Durham club requested. Most of the structure is built in 3mm MDF, but there are also parts made in 1.5mm grey card.
I have designed a system that locks together with pegs, this meas that it will hold together well, but be easy to rearrange!
Wall sections have push out sections that can be used as windows or access panels.
Finally, in this photo you can see a Reaper Sci-Fi figure, to give you some idea of the scale.
