I have lived in our small semi detached bungalow for twenty years. The adjoining property was bought just before Xmas and they have since been building an extension on the back. They did tell us before they started. They said that they didn’t need planning permission and there was nothing we could do about it. Our lounge is at the back and there is now a Nine foot wall right up to our adjoining fence and within 3 feet of our lounge window. Can anybody suggest anything we can do to get rid of this prison wall effect? Maybe loss of light regs.!
