Hi guys, just wondering if anyone has any info on an issue my elderly neighbour is having. Basically my neighbours house is located beside another house which has been vacant for years, the vacant house is slightly in front with just 3m between the two houses,they are basically stepped with 3m between the corner of my neighbour and the corner of the other house with a few stones down between them on the boundary . The person who owns this house has decided to renovate the house, there is a projection out the back of the vacant house at the moment on the opposite side of where my neighbour house is,and they are planning on building a wall to extend this projection building to basically square it off with the rest of building and then put a new roof on the entire house,probably with attic conversion also. This extension will be in direction of my neighbours house and when finished, there will only be about 2 feet from the corner of my neighbours house to the corner of the new extension and it will be less than a 1 feet from the boundary line. Just wondering if anyone would know if an extension is allowed so close to a boundary, my neighbour seems to think that the extension has to stay 2m away from the boundary. Hopefully this makes sense,I dont know much about this kind of things,just trying to get info for him as hes quite elderly and annoyed about this. Thanks I should probably add that there is no planning on this extension, but am told its not needed if its within certain dimensions.
