Moved to a new house last winter. House hasn't been upgraded in over 30 years including the garden. Explained to next door when we first met that we would be fencing in the garden for kids and animal safety and neighbour was happy with this (currently no fence between).
Now with the better weather we are doing the work. Neighbour knew what we were planning but obviously had a think about it and is now not happy. We explained it was all on our side and wouldn't disturbed her. She agreed she didn't like change and just wanted to know more which we understood.
On the other side the house is empty has been for years, owner lives abroad and hasn't been home for a number of years. There is a neighbour who does keep an eye on the house but I'm not sure where he actually lives on our street (fairly big street). Our neighbour who was concerned said she hoped we would be in contact with the other side before doing any work. We pointed out that when we moved in the fence between us and absent neighbour was in a bad state and had actually fallen down into our garden so nobody was actually maintain the garden/fence. We temporarily fixed it without giving it a 2nd thought.
DH has today just gone out and started work on the new fence saying we can't put off doing the work while we try and get hold of an absent neighbour. So are we bu to just go ahead. Any mess made will be rectified and the end result will be a safer and better looking fence.
