hi,thanks for all your replies...thought i would give a quick update!!
i have been trying to get the planning people to help explain why it is that at my pre application meeting they thought it would be ok for a shed and that i should have plans drawn and pay for my application which came to around £800....then on the day my notice period was up to phone and say no! and also why did they visit the site and speak with my neighbors(who did not object)if they had no intention of granting permission.i got legal advise(as quoted in post)which cost me another £800 for the adviser to put in writing what i already knew...very frustrating! i have asked the planners for help and they are not interested....i have put a pop up caravan in the woods for now to store my tools.i am also a member of the british beekeepers association and want to keep a couple of hives which also makes it difficult. one thing i have learned is that the national park does not care about the land and are not there to help you which is really sad....we have transformed this neglected bit of land,we are also working with friends who are knowledgeable about birds and put up a few bird boxes and also started keeping records of their activity.
happy new year to you all,
thanks rob
