OK OK I know it is a scourge etc.
I have a long garden and two old leylandii (60 footish) at the very back. They used to block the view of the council scrap yard which backed onto us.
Two years ago they erected four squillion houses on the old scrap yard. Including 4 along the back of our garden - with foundations TEN FEET from the leylandii.
Of course, the gardens there are only 10 feet long and nothing will grow. The leylandii branches touch the back of the houses.
One of the residents has now asked me to remove my leylandii.
What is the right thing to do?
