Who in their right mind would construct a house that close to an HV line and transformer?.
I'm guessing that the lines were there before the house was and any architect with any brains and a measuring tape, would have known that his design would have taken that side of his "creation" well within the safe distance from this equipment, even before the slab was poured.
One other thing that springs to mind is, how is a line crew supposed to get a bucket between the house and the transformer safely, to do any work on it?.
IMO, that tree needs a haircut for a start.
