Im a little suck with this one so any help would be useful.

Bit of background.

I have one problem neighbour which I suppose over 30 years and bordering 5
properties isnt too bad, we only share a 10 foot segment of fence at the
bottom of our garden with them. Yesterday the chap decides to do some
pruning of the plants in my garden that he can reach, long story short, I've
lost all the privacy in garden and my living room. There were 2 leylandii
which are now shaved to the trunk and an old fashioned mock orange from back
when they were large very highly scented flowers thats hes reduced to bare
stems around 5 foot high this had particular sentimental value.

I have two questions.

Is there anything I can do at the moment that will allow light in so the
tree can thicken up on this side where he cant reach but at the same time
prevent the neighbours looking directly into and therefore through our
entire house Is there tree coloured fleece or something I can weave in
whats left of the trees?

Will this have killed my mock orange - I've been trying for years to either
get a cutting to strike or a layering to take. Each time Ive ended up with
no root growth at all and dead twig. I would have moved it to another part
of the garden but didnt want to risk killing it.

Im open to suggestions. .... moving house is unfortunately not an option.

Lard.
