Lets create a hypothetical situation here with the aid of MS paint!
Much of it is self explanatory but the light yellow bit is, for the sake of arguement, an empty paved area and the brown bit is the wall of a building. The paved bit is owned by the owner of the building. There are no signs or restrictions other than the double yellow lines.
Would one expected to receive a ticket from the local council for parking on the paved bit?
There is, of course, no truth whatsoever in the rumour that this is a rarely used road near a University, or the terrible lies that the building in question is also owned by the Uni, or that it's opposite a lecture theatre or anything like that.
So opinions? Would you park there?
