[member=160088]BrimwoodFarm[/member] the planning department do not understand every aspect of planning, permitted developments or historical rights.
Look into certified locations, this is quite a good way to work the system, you do not need pp for a CL you require a licence provided by planning department. Only highways or English Heritage, or Enviroment agency can stand between you and a CL licence.
You will need a toilet/shower block, which is worth while applying for as a timber temporary building if they refuse go for a towable trailer :-) here comes your first static.
Once you have done a couple of years of tourers coming and going, (Open it for camping to others just so that people see vans coming and going) then drop in another static behind the toilet block, 4 years on you apply for a certificate of lawfulness.
If you want residential permission you need to register your driving licence, passport and bank details at that address, it needs to be done day 1 of the static going on site otherwise the 4 years become 10
