1066--No, we are not allowed to stay overnight on our allotments. Indeed there are a few that do allow that. I don't know for sure, but I believe it has to do with zoning and /or the technical (legal) definition of what our allotment club and complex is.
I do not know if this is a club rule or something dictated by the council --it was like that when I came and is still in effect.
I don't mind allotments looking ramshackle to a degree. I mean in my mind an allotment is "typical" when it is put together from odd pieces of this and that. Having said that, there are rules on size, colour and orientation of any sheds or small houses...even greenhouses that one may want to place on the plot. I first thought that this was just our club being awkward, but discovered that they simply included council rules into the bylaws.
There are more examples, such as people having to keep the canals that border their plots clean so that the water is free-flowing.
Ahhhh--bitterballen! I get the urge to go into town and get some right now, having read your posting. We have lots of little things to eat like that here, as you must know. I like getting little snacks when I am shopping or out and about.
