AIBU in being irked that a neighbour who lives diagonally behind us knocked on my door the other day and asked if we could cut our tree? It is a Sycamore (actually there are two side by side) and it is established. It was here before we bought the house and was pruned back hard (18 months ago). The neighbour complained that she had no sunlight in her garden last summer because of the tree. It is not wide but it is tall (no leaves at the moment so only an issue in summer) - about 18ft. I told her that whilst it may be a nuisance for her, it is a benefit to us because it provides screening (which is great when we want to use our garden). In the winter she can see straight into our house from her bedroom window. I also told her that we would not be paying a tree surgeon to cut it every year. She then offered her to send round her son's friend (a tree surgeon) next week (who would do it as a favour for them) and that we would only have to contribute towards the cost of removing the branches. However, we discussed it and decided that we would prefer to employ a tree surgeon of our own at a time that suits us and that when we do get it cut back, we will not take as much off as she would want. I think if a sunny garden was that important to her she should have bought a house with a large garden with a southerly aspect instead of a west facing 35ft garden.
