OH MY GOD!!! Someone couldn't find a better place for that fusebox??? I'll second, that "shack" is wayyy past it's expiration date, ready to be put to rest by Caterpillar.
I can't imagine looking out the window thinking.. "Gosh, thats a beautiful view of a.... fusebox!"
Where does the old romex out the top of the fusebox end up? Seeing the boarded up door and the 2 different exterior surfaces hints towards some kind of alteration of the building. Looking at the shadows on the building, I'm afraid to say, I think the rotted looking thing is (was) actually SE cable at one time... (Maybe when Herbert Hoover was in office
My guess is an attempted remodel by the HO and maybe one of his buddies, relatives, etc. about 50 years ago and they simply lost interest.. (or ran out of beer)
