Our master bedroom has just one "standard sized" closet (the width of two doors, with just a shelf and rod inside). Our guest room closet is the same size and just on the other side of the back wall of the master closet. The wall is not load-bearing, so we've been told we could combine the two for a larger master closet (and bump out another wall in the guest room to make another closet there). But what rod/shelf configuration could work in a "walk-in" that's just the depth of two regular closets, plus the four inch wall that currently divides them? Would this really get us any additional usable closet space in the master?
