Love the hidden storage that this headboard has. Hidden storage behind the headboard. Great idea to go up the wall/headboard side of a platform bed. Maybe open up the opposite side under bed for shelving.
a recessed nook becomes a headboard for the bed. I think I'd take the nook all the way to the ceiling to avoid it looking like you put the bed in a repurposed closet; and put the ledge up higher, so that you can recline against the wall
