Excavation for foundation for a house and a retaining wall has been done as close as 2 metres from my beech trees which are close to my boundary. The trees are 60 feet high at the moment and I have been advised by my neighbours tree surgeon that the height should be reduced to 15 feet. This seems pretty drastic but will allow it if the trees could come down on his house. Could you advise me? The house is below the level of my boundary and the second storey is on a level with me.
Cutting 60 feet beech trees down to 15 feet will spoil the trees and leave very ugly stumps for many years, until they re-sprout, and even they will look bad when the leaves are off. When they re-grow, beech tree that have been cut hard will develop poorly attached branches that can fall.
Probably the best solution is to take down the trees completely and replant with new trees, possibly smaller in eventual size. It might be possible to plant these at a semi-mature size to speed up the restoration. The neighbour might be minded to pay for all this in order to have the trees removed.
Whether the trees could come down on the neighbouring house depends on how far away they are. If they are 60 feet tall, they need to be 60 feet away minimum.
