For housing to be useful and functional it will need to have all crafting stations, bank and guild bank/store access, and several crates or closets to store and organize huge quantities of gear.
It would be really cool if it had one of those red portal thingies to teleport to any location and special crafting stations without cost.
All my alt toons should be visible lounging around as NPCs and interactive to quickly change toons.
Having writ board and drops would also be very useful.
Having wall murals that show achievements, trophies, etc.
Oh and a special House Carl that can double as an adventuring mule and fight buddy like in Skyrim.
