My house should have a pool, a start field for my dragon pets, that dwell in my basement, and perhaps 2 or three gold respawns in my treasure chest. If a GM comes around about once per hour, I would appreciate that, maybe I have some new stuff to install

Now for real:
Houses should be a bonus for long playing. They should be expensive and only very few players should have access to them. Therefore we install buildings only for groups or guilds, not for individuals - they are too expensive for one.
If you want a house in the next version, I would suggest, that you find some other players to share it with you (I guess you already have, right?). Then build only one story now, and upgrade it later, when you have more money. We will then install more stories or additional furniture. See the other thread for prices and examples.
