I live in one of 5 link detached bungalows. The link is the garages. Between the bungalows behind the garage is an area by the side of the bungalows where most of us have erected lean to type constructions which are free standing but enclosed. My neighbour has erected a lean to but has fixed it to my outer wall, on his side obviously. He has also fixed the pvc door frame directly to my wall. While i understand that this does not break planning regs can he really do this. It effectively turns my bungalow into a terrace on his side and i am worried about selling in the future.
