I imagine something in comparison to Residence / Advanced Residence. It would work well as either: 2 workers and a increase of 2 times(?), upgradeable to 2.5 (?). Or only 1 worker and it's worth 1.5 / 1.7 times the amount of a regular agridome. I think the extra expense should be in materials and power (if it's more automated).
I don't know why, but 4 times the amount seems excessive to me.
However, I do like this idea! (thumbsup) The finer points might be something that would need to be play balanced/tested.
Perhaps if massive colonies are a "goal scenario" in OP3, there might be a need to have many types of advanced structures to make late game colony expansion a little less overwhelming. (DIRT, medical center, rec facility, etc...)
