I cranked the telephoto up to x15 and got this.
It’s not clear what it is for. It doesn’t look like a house exactly. On the next hill, about 500 feet away, was this structure.
The blog photo might not have enough resolution to see but it is a smaller building with two big holes in the roof and a bare tree in front. I made up a silly story in my mind about how that was the loser’s house and the winner could look down on their derelict house.
