My neighbour has been granted planning permission for a 3m brick extension adjacent to the dividing wall of our semi deyached properties.

When I queried this with the Planing Office I was told that the 45 degree rule from the nearest window would not apply because I have a conservatory. In this instance they say the centre of the conservatory applies. I think this is incorrect.

I am now looking at a brick wall about 3″ away from my conservatory.No repairs or maintenance will be possible.

Can you confirm how the rule should be applied?
