Here is a try of one continuous fold.
I oredr to work with constrain of dimension of container panel this fold was unfolded iplane and set on unfolded plan of 4 container flat.
Then entire sheet of panels are folded.
Starting from this space resulted from folding business now I try to embed series of furnishings, interior fixture, etc...though fold itself isn't geometrically comprehensive.
Last sc shot is first try to make one fold into staircase.
