The Bathroom (It hasn't changed, but damn isn't it nice):
The Dwemer Library:
The Ayleid Library:
The Awesome Alchemy Lab:
So, what do you think? ;)
Update: Room207 brought it to my attention that the bathroom was way to modern compared to the rest of the house to which I say: Better? :)
Update Again: The Kitchen with (hopefully) less ultramodern shiny kitchen fixtures.
