The black transformer box for the low-voltage lighting is mounted to the wall just inside the door. The 120V side of the wiring was one of the most annoying parts of the project. Inside that bit of wall, there's a little bit of open space and a whole lot of studs. I'm not completely happy with the end result, but at least it's not too visible. As far as I can tell, it's completely up-to-code, too.
