To be annoyed at neighbour drilling into my wall?

[Bezm]

I have just seen that my neighbour is having a plastic roof put in the back and is attaching it to my extension wall by putting up wooden battens. My extension is about 6 inches from our boundary. So not only has he drilled into our wall, but has put the roof over part of our garden. When I asked the joiners what they were doing, he came out and was very rude!
I pointed out that he'd not even bothered to ask about drilling into my wall or putting the roof up over my garden. He said he couldn't see a problem and didn't know I was in anyway!
I'm fuming!

I wouldn't buy a house which had an ettachment from next door onto it over a boundary. It would concern me enough to put me off offering simply because I would worry that they were feisty arse holes and that it would be too much hassle to sort.

If you ever plan on selling I would get this sorted asap.

Crikey my heart rate has gone up reading this from the start!

Glad he's seen sense.

What's he holding the roof up with then?
