I have a room which I would like to turn into a hallway and a room.
The problem is that if I stud out a wall the room, with the minimum
width hallway, will be just less than the magical six feet wide. Would
I be violating any codes if I made the wall out of a piece of 0.5 inch
CDX or OSB held in place by 1x3 molding at the the top and set into a
groove 3/4" deep routed into the floor at the bottom? I would then
panel both sides with the paneling edges staggering the CDX edges and
use surface mount electrical. I could even use tongue and groove
plywood.

Is there any proper way to make a THIN wall?

Thanks.
