Under a mat hidden cellar.
Hidden room wall panel.
In the photos the 1 x 8 s are green.
Beadboard overlay raised panel flat panel batten and board.
Because it s a storage room we slide open the wall do what we need to do and then slide the wall closed.
Raised panel is the most traditional and respected form of wainscoting.
This will make installation faster.
The 1 x 2 s are hidden covered by 1 x 4 s painted white.
This combination made a pattern of 16 wide panels due to the true dimensions of the nominal lumber.
So the wall slides open when i need it to.
But it hasn t been a problem.
The best hidden doors aren t even there to the naked eye just like this one that looks like it s part of the wall but opens to what seems like a rest room.
Yes the wall slides into the hallway there was no other way to do this.
I thought this 16 pattern would be important to match the usual spacing of the wall studs but since i was gluing the boards up it was immaterial.
