Man, those buildings remind me of arcologies. Awesome idea, though, especially if there was some space next to the crops that you could use as park land (or if you could otherwise visit/help out/etc.). Not as efficient, maybe, but better for the community.

Of course, my big concern here is where they're gonna get the energy to run one of these. It'd probably use more power than a datacenter, and those are usually way out in the boonies, while one of these'd be as close to the city center as possible.
