Just wary of paying a load of money out for it to be declined as by looked of it could cost £500 - £1000
It will cost you lot more in time, wasted money and stress if they make you take it down afterwards.
Planners are usually more than happy to give advice over the phone, and it's far better to get them on side in the first place than give them reason to go after you.
I worked for someone who built stables and a big barn, thinking it would be permissible as agricultural buildings, and then had years of strife getting retrospective PP. It completely scuppered him with the planners when he wanted to get PP for a dwelling. They turned it down several times and then sent him an enforcement notice to remove the caravan he was living in meantime. It was a horribly stressful and expensive time all round.
