Of all cities on minecraft, one thing alway miss... a farm ! how did you get the food for your citizens ? 

Here the answer, a huge modern vertical farm, approximativly 20,000 plants ... this impressive multi-fonctional building can be modify for any farming opertation. it can be a pig breeding (or other )or a sample farm ...

now, why normal ?, because it exist an completely automated version powered by minecart and redstone ( where when you press a button,a minecart come to your house to pick your choice.

maybe later, there will be an distribution building (and storage) connected to the production center and it will be powered by piston,redstone and minecart .
