Wow, I had not noticed before how much of a grade / slope there is in front of Norah and Compo's place. The picture of yours, Graham in post #188.
Or maybe it is. an illusion with the wall and railings while the actual pathway is flat or level. For those who have been there in person, your thoughts. The angle must help the dust roll away downhill while Norah swept!
Judging by the stones on the wall it seems like a several foot rise on the left side by the white chair to the steps on the right side.
