Having just read someone else's request for advice regarding their neighbours overgrown hedge I thought I'd throw in my own two penny rant!
My mother has lived in her house for some twelve years or so. When she bought it there was a lovely sea view but the neighbours trees (conifers) were starting to slightly obscure it. She asked, at the time, whether they were kept in check and told, by the agent AND the previous owner, that indeed they were....
As of today, the trees continue to grow and are now almost completely obscuring any view she once had. What makes matters worse is that she herself now wishes to move to somewhere smaller and EVERY viewing she has throws up the same old question "can those trees be cut?"!!!
The answer is NO! They are probably 40 feet or so in height now and steadily growing. Apparently, legally, you have "no right" to a view!! Even if it can make a difference to the price of your house of hundreds of thousands of pounds...
And.... as for "a polite word with your neighbour about it", you'd have to meet the man in question to fully appreciate his personality but, trust me, that is totally out of the question! Why are some people SO aggressive and unreasonable?!?
