So, I think I'm at home now for the long run, in an effort to rekindle the commuting spirit, I have a long garden which I really want to put an office at the end of, a shed will do, around 8' X 10'

To make the saving for such a thing, circa £3000 worth a little easier, I need to either find a way to recycle a lot of stuff or make a passive income.

Could any of these be realistic?
