If your barn is used mostly for agriculture and you park your plane in the corner, as a land owner, you are allowed to stay and go, within reason, as you please. As you are the owner occupier of the land there is no valuation tax...period, they will tell you otherwise..or try to. Valuation will occour if you have a business you run from a change of use agricultural barn to hangar. Use the words private recreation flying.
Fenceing of the strip will be fine as long as "no rights of way are blocked", 30m is ok, mine is 25m still no problems.
I,m not a legal bod, just a few years of experience, and yes you can get permission for a strip in the UK, providing you have 10years use and go for a certificate of lawfull use,CLU, and can prove it...simple !
