Our NDN with whom we have a very very difficult relationship (they hate us due to our recent extension) has planted 2 fast growing spruce trees on the boundary and within 1m of the hated extension. The trees will not block our light, but they can grow to 30m. As these trees are not a hedge we would have no rights to restrict the height. We are very concerned that they could cause damage to our foundations.
This has definitely been done as an act of aggression, but apart from getting our solicitor to write a letter, what can we do? Do we have any rights.
