I watched one of the videos, how to make insides.. now the style really isn't my style.. and think alot more could be done - but the basic structure of setting up a house I agree on. (on a smaller scale, as I dont think you need anywhere near as much floor space)
I certainly agree that the insides should look like the outsides, I am strict on my lats about that. I remember I made a couple of examples when I was working on a old N-Pulse project.. thought they could help out here too. (they are gifs, so give a sec to load)
