The various Boxes (around 30) were made from PVC flooring fake-wood-boards things I cut with a scalpel.
Glued to wooden blocks or any other box shaped object in the right size I could get a hold of at the time.
Some boxes are hollow to store artifacts in them (Ark of the Covenant and such).
The set of stairs was built from polystyrenes sheet, or whatever that stuff is called.
