My neighbour recently submitted an application for permission to build a single storey extension to the side of their house for use as a pre-school. They live at the end of our small cul-de-sac. Can I make a objection based on the fact that this is a residential area where children play outside and increased traffic could possibly be dangerous? It seems (so far) that 3 of us neighbours don't want a pre-school on our road, we don't object to the actual building but just its use. Any help will be greatly received.
