Does anyone know how long an average garage is? (How long is a car?)
If the 'drag marks' spanned 8 meters (is that correct? I don't have that in front of me?) and 8 meters = 26 1/4 feet, and they measurement (of 8 meters) likely includes turning the corner to the place on the driveway where the drag marks ended, then we can probably figure out if that door belongs to the garage or the house?
I noticed in the 'garage interior photo', that my bearings were off, I had assumed that the 'work bench' was along the side wall, where the garage abutts the house, but now I see that there is a car parked in the garage in that photo, so the 'work bench' is actually in front of the vehicle, so I don't think we can see the angle of the garage which would show whether or not there is a door into the house?
I would agree with you that not many garage doors would have a screen door.
It is also odd to me that there is a little step there on the sidewalk, and the door falls on the lower level of the sidewalk, which to me, would almost indicaate that the lower level of the sidewalk meets with the garage, and the upper sidewalk meets with the house? Notice there are also 2 trash bags? (at least that's what they look like to me)?
