@cyberknight Did this ever get resolved.
My neighbour has just added to the pile of building sheite opposite my house on shared land - only saw if from my shedoffice as it's behind a tree that has grown well since November when he dumped the last lot.
It's 4 1/2 foot tall, of panels, insulation etc. He's also plonked a shed on his driveway at the front of the house - probably for the kids bikes (there are 9 children living there). PS Bet he still has less bikes than I do !
It's shared land in the deeds, but he think's it's his.
