I had a query with Google maps some years ago (bus times)and it turned out the had different data information for the pc version v the Android version.
Well Bing on my Android gives me the cracked concrete at StreetView, not paving slabs.

maybe it's different on your machine.
Do you remember that big ash tree when you took the photo?
Lots of green ash leaves in the gutter. Maybe they'd done some tree surgery. In your photo the wall looks recently rebuilt & if those paving slabs are 2x2 it would make it wider than my bing view.
The bing view also confirms the position of the water stop-tap lid. (ok, maybe every house has one similar!)
