Our garden is north facing. At the bottom of the neighbour's garden (to the right of ours) are 2 absolutely giant leylandii. I would say 30m tall. One of the leylandi's trunks leans on the fence between us but is on their side. Because of that virtually half the branches of the tree are completely on our side of the garden.
We have a shed that sits under the tree on that side of the garden and as the tree is growing, it's becoming more and more problematic. Nothing grows underneath it within about 20 foot because it sucks up so much from the ground and it seems to have a few new branches that are damaging the roof of the shed.
It's not blocking our light (because the garden is north facing). The neighbours are enormously difficult people who have a paranoia about their own privacy (hence the 2 giant trees). They also have hedges above the fence line on both sides of their property.
I called a tree man to have a look at it and because of its size, he does not want to cut the branches on our side without counterbalancing it on the other side. The neighbours do not want it cut back at all. If it's not safe, we can't cut it (understandably) but I'm just wondering if anyone has been in this situation. Are we stuck with their giant monstrosity if they keep saying no? They cannot cut it from the top to stop it growing because it's too tall.
