I have recently moved to a house in a typical surburbain area. At the end of
the garden there are some conifer trees that must be over 30 foot in height.
With the way that the sun moves throughout the day they do not affect the
light in my garden but one of my neighbours gardens must be in constant
shade. Nothing has been said by the neighbour but I feel I should cut them
down to a more reasonable 15 to 20 foot. I would like to keep some height as
they obsure the view to a rather ugly building behind the houses.

Am I under any legal/bye law obligation to cut the trees down to a lower
height?.

Due to the dry summer the trees to look abit brown towards the top and
edges. If I cut down at this time of year am I likely to kill off the trees.

I am planning to build a large shed in front of the trees so I would rather
do any cutting now so I do not risk damaging the shed at a later date.

Eric.
