Boxed out

I wish I needed boxes but I don't, because I have all the boxes a life could need.
I have collapsible boxes, convertible boxes, Ikea boxes, Daiso boxes, recycled boxes, repurposed boxes, even organic boxes and I'm afraid mon ami, that a box isn't the solution.
I need another level. A floor with a thin base which can utilise the space above as below.
I do not need a housing solution, I need a space solution.

Take for example a family that lives in cosy houses but since there are too many such houses it takes up the road, so the family puts those houses on top of each other and builds an apartment.
Putting them in a box would be shoving those inhabitants without their houses in a big single storey bungalow where all the families get mixed, lost and it gets chaotic and the only time I love chaos is never.

So yes I only need a floor to vertically align all the stuff which is pretty well kept in their desired gated areas and organised in a way I could find it blindfolded.
