I need to get some cobblestones for my driveway. Can anybody recommend somewhere that is within an hour or so of North or West London? I would prefer to go and see them in person, but I really only want to do that if they have a good selection. I'm after traditional looking cobblestones in a mix of greys.
I'm aware of Rock Unique in Kent which are very knowledgeable, but I wanted somewhere else to compare (and Kent really isn't that close to me).
