This was no electrician. I can definitely see the difference between the original rough-ins and the previous homeowner's half-*ss fix ups.

He didn't stop at elecrical either. There's a window with glazing on only three sides.
There's drainage that runs all the storm water into the neighbor's yard.

There's a receptacle that he didn't have the right cover for and this time instead of cutting the cover, he cut the recep.! I'll take a picture of that next time.

So take heart. An electrician did not do this.
