I'm really hoping that someone here will be able to advise me.
A family member lives next door to someone who has just built a wooden extension to the rear of their house which is in breach of planning. Both of the immediate neighbours have done this but one has a bigger impact. Neither contacted the planning department.
We contacted the planning department in June and other than requesting more information when we chased them we have heard nothing.
Aside from the visual impact, loss of privacy, views etc, they built along the boundary line with no discussion in advance.
Since these extensions have been built, our family members garden has started to grow moss instead of grass and has sunk as it's now lower than the path when previously it was level. It is also soggy for longer when it rains.
I have suggested that they need legal advice but they are worried that the neighbours will escalate their hostility- they have already told family member that "if you don't like it then move" (difficult when the house has been devalued). I'm going to help them chase the council again tomorrow and will escalate it to our MP if they don't seem to be taking it seriously. I will try again to persuade them to take legal advice.
In the meantime, is their anything that I have missed or anything else that we need to do to get this resolved?
I have attached a picture.
