How much "big" will be ARR Housing?

[Zenaku]

Yoshi-p said it going to be somewhat big only 20ish homes can fit per instance zones. He also said they be a small,med,large and most players would get med due to how much it cost at first they wont be much to do but they keep adding with updates. I like the idea i can grow stuff outside my house and have a chocobo area in the back. So if you think about that it going to be pretty big but they wont be much to do with it too they release more in update. I don't see it being as big as that video but you never know.
