For smalls and mediums it's not so bad. I have a small FC house and I can fill it up and make it look good. I did my other half's personal med plot and the same, filled it up made it look good, both have slots to spare.

Then I get to my personal mansion and even at 400/400 it feels empty. I even blocked off half my basement to avoid having to do anything with it. Mansions are too big for only 400 slots, we definitely need at least another 100-200...at least.
