It isn't luckily too near the house as that would be a total pain. We had the sense to make the boundary far enough away. It is just that we like our quiet and have built our place so as to not annoy any neighbours. They are already on the "loud music" thing and this is just another annoyance. Also in conversation they agree with us about the garage that the previous neighbours were going to build right on the boundary, 5 metres high, so we planted huge trees to screen it. They seemed to agree about how much land they had and that there was no need to do stuff so close to the boundary, yet here they have gone and done this. With 6000 sq metres? And their house is much further away? I am fervently hoping they are just storing it there but W thinks she has seen piping and electrics to it. Also they tell us they too are going to put a "hangar" on the base the previous lot constructed right on the property line. Despite what they said, so I think they say one thing then do another.But why will this upset you, unless it is right by your personal and private "you" space?
Where they put their Hot-Tub might be better than them putting their "dunny" in the same spot perhaps?
As I said, we are giving them rope at the moment. I think with not having had neighbours for 19 years we have been a bit spoilt.
