Okay going to have to be a very brief update on this as a solicitor in civils and property has advised that making public spectacle of the issue might not help the case (even though I have purposely been vague; only mentioned Derby, have not named anyone and also not posted photos even though requested!!).
Local radio had my mate on air yesterday and again later in the afternoon after a few people had called in; he is now the local celeb in the street.
The neighbour didn't come home yesterday evening and my mate has been told that he is staying with family as 'he fears for his safety'; what a crock!
Two builders came round. One was another friend of my mate and the other was as a result of the radio interview. Both have said that the outbuilding does not have proper footings to support the brick structure and it simply has paving slabs underneath it to level the ground. Some of those around the rear of the building have already cracked and show sign of sinking. We are talking a sizeable brick building about 3m x 4m. One gable end if complete brick, as is the rear wall and the other gable end and front wall are about 6 courses high with a timber frame sitting on top.
The builder who turned up as a result of the radio interview says he knows the chap who did the work and says he is a good guy and wouldnt have done this knowing he was going against the wishes of my mate. Whilst we cant say otherwise, why would a builder construct something that was visibly over a boundary?? Also I cant comment on the skills of the builder who done the work but why not put in proper concrete foundations??
All in all it looks like it is going to be a legal mess. The legal advice so far is that a letter will be presented to the neighbour asking him to move the brick gable end 1m so that it is not on my mates property and also allows the fence to be reinstated with no further risk of boundary issues. However from what I saw, if he does this then it will a] cost an absolute arm and a leg to do and will b] make the outbuilding a lot smaller than it is now. The other option is to dismantle the structure completely.
On the basis that there isnt any proper foundations and the paving slabs are already cracking, the solicitor has also suggested that a proper survey is carried out to see if the building is safe and not at risk of moving. There are a few mortar cracks visible but I dont know enough if that is a serious issue.
So whilst I will update where I can, it looks like everything is in my mates favour at the moment and I cant see how the neighbour is going to get around the issue that he has to resolve the issue quickly
