Council say I'm outside the conservation area and if the trees don't have a preservation order, there's nothing I can do.

Also, because I wasn't able to give them an exact address where this work is taking place, they can't tell me if a planning decision has been granted to allow removal of trees.

Thought I'd pass this on in case this is useful for others to know.

Am going out now, because it's depressing listening to it going on!
