NC as could be outing! One of my neighbour's has a garden that backs on to the bottom of my garden. No problem with that of course and there's a fence for privacy. They have decided to build an 8 foot structure though, so their children can access the tree to 'hang out' in the very broad branches. It now feels like an observation tower as the tree is right on the boundary so looks over my whole garden and into my kitchen and childrens' bedrooms. WIBU to ask them to remove the platform and therefore access to to tree?
