First section in place, simple 2x3, 1x2 and Luan (1/4" birch plywood) construction.
Notice the ceiling? that was my guide for measurements. This piece got screwed in to the door frame, also from the outside, and down into the floor.
The face went on next, this had to be rebuilt a few times... looked nice here, didn't figure the doors out until they were hung. That center board was supposed to be flush with the cross piece. Oops!
Put the other side in (before I figured out the front rebuild)
After rebuild # 3, I think. Doors hung, latches lined up... good.
