Our house came with an overgrown but clearly fertile veg patch - if I have enough, time, this could be a cheap year for veggies! - several mature fruit trees (2 x apple, 2 x pear, 2 x grape, 1 x nectarine, 1 x lemon) and 3 compost bins full of brown, crumbly goodness. We now also have a large water tank (I suspect there will be hosepipe bans in Chch's future) and a worm farm. Land area minus house area is ~700m2..?
Most people I've met here have some form of grow your own patch, usually quite small, but every little helps
