The bord is MDF coved in cut card for the flags and brick work, it took me so long as each brick was stuck down individually. The man hole covers in the brick zone each have one of the suits on them. The flags have bean arranged to show deployment zones ( in only two corners in hindsight wish I had don all ) centre lines and 6inch from center
The tower is made from FoamX (sintra in the U.S.) I love the stuff
"Foamex is a brand name for PVC foam sheet (or foam PVC), sometimes known as Forex, Foamalite or Palite. Don’t confuse it with the soft, spongy board known as “Foamcore” which is sometimes used for mounting pictures"

Unlik fome bord it is much tougher and ridged, but with a bit of heet it becomes malubel. It can be stuck with super glue or poly cement. It can be scored and marked to create textur and takes paint really well.
