Re: Show us the circuit breakers!
"And no, putting in more outlet holes in the drywall doesn't hurt the structure of the building. "
That's not likely to be drywall (or plasterboard as we right-pondians call it). Outside walls on a house like that are likely to be brick cavity walls. However, even that many are still unlikely to damage the structure of the build enough to worry about.
Although now that I've looked at the listing for the house and seen the outside, it could be brick and stud, or whatever they call it. One course of brickwork then studs and plasterboard to form the inner part of the outer walls. There does seem to be a remarkable number of recessed spotlights at about knee height, even in the bath panel and behind the bog!!
