Hi, my attached neighbours have recently done some improvements to their house and consulted me on anything that affects my property. I've not had issues with anything. However their builder has now removed the shared drain pipe at the front of our houses (in the middle, slightly more on my side) & replaced it with a raised grid about 10-20cm. To me it doesn't look right and stands out (before it was just a discreet pipe going into the ground). I was not consulted on this. Would this bother you and if so how would you approach your neighbour about this? We get on well so I do not want to fall out with them but equally don't want to see this eyesore every time I get gone. Thanks.
