I live in Hartlepool, and so I know it's hard to get a plot to work on. I'm already sharing sand am at the other end of town so can't offer any personal space, but why not see if you can put up a poster in the King Oswy and Brus Corner shops asking if there's anyone who would let you do their garden for them? often council or ex-council houses have decent sized gardens. Sometimes there's an elderly person/couple who would appreciate someone taking it on.
