Strangely, i asked my permission owner about putting a "shack" up on my permission. Just something to shelter in, make a brew etc. Mr K said no problem, as long as it doesn`t get in the way of the running of the farm.
I`m scrounging/bartering some scaffold planks to build it with and a couple of rolls of felt will finish it off. I could get a couple of miss-fit upvc windows off my old boss too but i might want to move in and Mrs basil may have a say in that!
