On the other hand, he also mentioned back in Stormblood they were discussing the possibility of adding in apartment sizes. Similar to how you would choose a plot size for your house, you would choose an apartment size when you purchase. If you wanted a different size, you would give up your old apartments and purchase a new one in the size you want. Unfortunately, nothing has been said about this since so we don't know if the idea was abandoned or still being considered.

Certainly such a system would satisfy at least part of the existing demand fueled by a desire for more interior space even if it doesn't satisfy demand created by the desire to have outdoor decoration or a garden.
That would be great if he really said that. Just because it hasn't been implemented doesn't mean it's not on the roadmap. They may have just had other priorities and kept delaying it to "next year."
