We live in a rural lane and want to build a 1m wall in front of the house where there is currently a rockery. A neighbour has a driveway opposite and says he will oppose this as it means he will struggle to get large delivery lorries up and down his drive. He has previously complained to Highways about our rockery saying it is dangerous - it has been there for many years. If the council receive a complaint when we put in planning permission will they automatically refuse permission and can he rely on driving over our rockery to get lorries in and out of his drive?
