Ok Marianna is correct. That is Foggy's house as shot from the (moving) Summer Wine Tour bus.
I think there may be confusion between the 2 posts I made. The 2nd shot from the SECOND post is indeed the (in)famous lake and bridge near Jackson Bridge. I don't know if it is actually accessible to the public or not but as the Captain says,
previous threads indicate that it is on a private estate. The shot was actually taken from the location that is often seen of the boys sitting on a bench overlooking the area.
Dick, if you are suggesting the 1st pic on the 2nd post is a water treatment plant I am ashamed!
.
See if it looks more familiar shot from the opposite (and more common) direction
