I'm pretty new to permaculture, done bits and pieces about growing veg but we don't own our home (it comes with the husbands job and I've always held off doing much incase we have to move). The house is also positioned very high up on the fells, it's very exposed and windy, but I have a decent sized garden, a patch thats been used as the veg patch, a fair bit of hardstanding around the house (mostly concrete, where I have a greenhouse and I put my pots) and separate space for my chickens (there's a big pen but at the minute they are free ranging while I reseed the pen). I'm sick of sitting around reading things I want to do 'when we get our own place - one day' and not doing anything now so I'm going to take the risk that I might have to move and start all over again and actually start doing something where we are now.
I studied agriculture for a couple of years but something just didn't sit right with many of the things I was being taught, so I moved on to other things. I've just started another degree, in environmental science, and the more I learn for my degree the more the things I'm reading about permaculture makes sense.
Welcome Sam. Don't look at is as possibly having to start over again, look at it as good practice (and it won't be as worrysome if you make a mistake) for your future place of paradise. An opportunity like this might actually be a bit freeing...in the sense that maybe you will try things that you wouldn't if it was your own piece of property. Have fun with it. Learn all you can.
