I've got a small calor gas camping stove in my shed - two rings and a grill. Very handy if I want to spend a whole day down at the lottie. Managed to lay on a party for 6 last summer, with freshly harvested potatoes, salad, herbs etc. , followed by fresh fruit.
If you ever get a chance to pick up a volcano kettle at a reasonable price (the new price isn't reasonable!) then grab it. They're extremely efficient, and all you need is a few dry sticks.
No toilets on site granny - but we have very high and dense hedges. Plus, with four plots, we have had space to erect a little 'cubbyhole', so no chance of anyone accidentally spotting us! We were a little concerned about someone spotting us when we first took on the plots about 5 years ago, but now don't really give it a second thought!
