How deep is standard bedroom closet?
From a drywall standpoint, the 24-1/2 (I'd actually go 24-3/4") would be the most "efficient" and is kind of the "standard". Hang the back wall first. Rip an 8' sheet in half to stand up the sides (the 24-3/4" rough gives you a little room to play). Then run a header across the top of the front and stand up "legs" under it. (When hanging a whole house, there are usually "off fall" pieces to make the header and legs.) But you can make it whatever you want....
