Read the Local Plan, look at other devlopments and discuss with planning office. Currently looking at one of these but for an existing outbuilding and its still tough.
Additional option is to start using the site for perfectly legitiate but totally objectionable purposes, such as storing multiple brightly rainbow coloured shipping containers, and rusting cars (drained of all fluids so no environmental isues) piled on top of each other. Couple of years of that and they’ll welcome a nice house.
Either way dont be in a hurry!
