dangerous structure

[hill walker]

My neighbour has a partially collapsed shed close to fencing which he does not own (part is mine and part belongs to a social housing landlord). He has attached a rope from the shed to one of the fences (can't see if it is mine or the social housing landlords). The structure is leaning towards the fencing, so tying it to it will not stop the shed collapsing, but risks taking the fence with it when it does and injuring anyone on the other side of the fence when it happens. I have taken a photo and reported it via email to my social housing landlord in the hope that they will be able to do something about it. I am aware that I can report his shed as a dangerous structure to my local council building control department, but I am anxious about doing so in case the building control department then reports me to the planning department for having trellis on top of my 6 ft high fence. Both have been up for several years now and had to be erected because this neighbour kept throwing stones and glass at me whenever I went out into my garden. I got permission from my social housing landlord before getting the fencing and trellis erected. I don't want to report my neighbour's dangerous structure and then find that building control reports me to the planning department and they make me remove the trellis that is keeping me safe, but I'm worried about the partially collapsed shed causing damage to property or injury to people when it finally collapses completely. Am I right to be worried that the building control department may pass on the details about my trellis topped fence to the planning department, or is it safe for me to report the dangerous structure next door to the council?

My local council provides for anonymous reporting. Have you checked out whether that is possible?

Also, building control don’t usually concern themselves with planning regs, often requiring features which planning hasn’t consented to, like opening windows in side walls.
