Ah, I didn't even think of that... the roof of the barracks is stone-tiled and flat (I think I already described it as flat, possibly repeatedly, but I don't trust my memory). Concerning Zerulic architecture, note that it was the [I]exterior[/I] walls that were mainly white/beige/cream colored; the interior walls tend to be much more individual, just as the furnishing is.
Your link seems to give a 404 error when I try it, but I think I know what you understand. I don't like when rooms are lifeless like that, either... nor do I like exaggerated order, for that matter. If a room is meant for people to live in, I like to be able to see that such is actually the case. Cleanliness and order is nice to an extent, but where there is life I want to be able to see that life. I feel the same way about gardens, really... Almost everyone else that I know want to control their gardens, cut down their trees and bushes, keep their lawns neat and tidy, exterminate weeds when they appear, but I personally prefer the appearance of wild nature over artificial construct. It would take something pretty extreme for me to fell a tree or remove a bush, and as long as the grass isn't tall enough to hide potentially dangerous things beneath it, I like it that way compared to when it's short.
That's another reason that I never want to have to live in a proper town, let alone a city; that, and my self-diagnosed mild enochlophobia (fear of crowds) (I can be in a crowd if I have to, but I'll usually get increasingly anxious the longer I stay there and ultimately start hyperventilating and feeling a greater and greater urge to flee). Oh, and the light pollution. I like the stars, and I like being able to see them; I think they are immensely fascinating.
