It’s only one upgrade, and it goes to 4 spaces. I would not do this except if they have a super sale for upgrades going. You are much better off getting the 5-slot habitats that they offer every month and replacing one of the standard habitats, this costs „only“ 300 gold. Or get the one million coin habitat and do the upgrade to 5 slots, 300 gold as well.
