Thank you for the quick replies! The live area is the top and the neighbours side (have included 3 more pictures, 2 of my side and 1 birds eye view). There is approx 1 metre left live on my side as we stopped when my neighbour alerted me to the potential issue. That is the 3rd picture which refuses to display the right way up, apologies it is upside down despite rotating it. Hopefully these pictures give a better view and an appreciation of the space. My neighbours have always maintained their side so it did not encroach into their drive. We have been away for 10 years so the maintenance has been sporadic, hence the encroachment. The firs are approx 2.5 to 3m tall, my neighbours and I are ok with that. Given the small amount of green left, I am assuming this will take 4 years or so to grow back (if at all). If they won't sprout and there isn't enough to train, I could envisage getting rid of the branches on my side to allow space and more light for new leyllandii to grow from within. Thanks for the ivy suggestion, for now would rather not but will keep it in mind. Of course we could dig it all up and replant, however, I have upset my neighbours enough already with my ignorance, though it may be the best option!
Any further thoughts are much appreciated and happy to take more pictures but it will have to wait until tomorrow as the light has gone.
