Owners of a semi detached house in my street are going to put plans in for 2 storey side extension, the other semi already has one and the other side of them are 2 detached houses that have been extended up to the boundary which means if this gap is filled in there will be a bad terracing effect in a street of otherwise spread out semis and detached. It will look over developed IMO and I know councils didn't use to like plans that made a terraced effect but recently planning rules seem to have relaxed. I was wondering what the chances were of PP being granted or if the terracing effect would see them rejected.
