About two years ago, my neighbour turned a brick out house backing onto her property into a bathroom. Two walls of the out house are boundary walls in my garden. She had no permission from me but I came home one day and she had directed her overflow pipe, pvc bath drainage pipe and guttering all on my wall, it upset me but I'm a wuss so didn't know how to deal with it. Have attached photo for ref. Weird garden boundaries as row of cottages used to belong to one family so odd division of gardens. 1) overflow pipe 2) guttering 3) bath drainage 4) her property 5)my garden.
So recently in another part of the garden she has now started cutting my hedge back and moving the boundary completely, this is a totally different arguement and I am getting a surveyor to sort this boundary line properly. But in trying to move the boundary she has massively damaged our hedge.... And I'm really pee'd of with her taking advantage and want all her crappy plastic pipes gone now (for additional information she didn't want a party wall agreement). So can I saw them off cap the pipe and return them to her???
