Instanced housing + housing in wards for those who really want that.
Bigger apartments, ideally with a balcony or a personal planting area somewhere outside the building.
Ability to move items in all directions so as not to use glitches to move things up.

But I mean... I feel like this is a very exhausted topic. By the amount of threads created daily about housing, it’s clear everyone is unhappy, but if the devs don’t make any changes to housing in general in the upcoming expansion, what chances are that they ever will?
