Hidden Door

I found a broken bunk bed in the trash. I used the side rails to make a box to block the entrance to the hall.

I re-used the screws from the bed.

I put some 1x4 inch plywood on the back of the top and some mirror squares over that.

I used a piano hinge to attach it to the door jam.

I finished off was a handle on the inside and glued some magnets to hold it shut.
