Good on ya lad, i run an allotment of 90 plots here in the black country. I keep chooks, bees, have a 30ft greenhouse and a smaller one for hardening off. i also built a log cabin on my site with a kitchen and wood burner. Its a right little hide away.
You stick with it son, if you get through the winter you will be well away, the shrooms grow on fertile land so under that grass you will have some fine soil IMO.
