A swift visit to check that the walls behind the shed still stand and the good news it that they do!
I visited the contractors re the wall and it appears they will be starting the works in the next couple of weeks, I have been in touch with the council and let them know what's happening and they have asked me to keep them briefed.
I had lost watering cans and large pots etc. onto the neighbours plot and a Rubber Dustbin Lid that just appears to have vanished into thin air. I did recover a number of items from neighbouring plots.
