And the blue tarp from the court pic's- note it appears to be a van door opened on the right of the pic

Can anyone match up the area in the photo to a place at the 'farm'? I found these 2 photos which show a stone building with a dark brown vertically sided barn-door.. but I don't think this area has a concrete base (and the brown doors are trimmed with white, which does not appear to be the case in the picture showing the tarp)... but it might be on the right track at least?
These pics are from various news articles surrounding the time when the farm was being searched.
