I'd like there to be some 'cabin in the woods' option too, perhaps with a mini quest to get it.
Yes, it would be interesting, and rewarding to find a significant other and get a home as the result of completing various quests.
That cabin in the woods with a cozy fireplace, and all the required goodies would be quite nice.
The mead hall, suggested by SwedishBerzerker, sound good. I have been thinking about a Viking sytle longhouse, and a mead hall just might work.
If I have to build my own, I will probably choose an enviroment like the Fall Forest. However, other areas in the countryside could be interesting.
