[tahjdqus] Reconfigurable internal walls

To what extent are our household lives shaped by what will fit through doors, either exterior or interior?

Can technology deliver a vastly differently way of structuring the interior of a living space, obviating this problem?

One radical idea (I'm not sure this technology exists) are curtains.  They are attached to the ceiling by magnets which can freely roll anywhere on the magnetic ceiling, so they can be easily reconfigured, or opened to make an opening for a wide piece of furniture.

Upon flipping a switch, the magnets lock in place, and by "magic", the formerly pliable curtain stiffens into a solid, soundproof wall.

Inspired by this refrigerator probably not being able to fit through standard doors.

Getting things to different floors would be the next challenge.
