they show you the kitchen and a shot of the bathroom sink in these pictures, actually. it's just so minimalist that it's not that obvious. not quite to my taste but that's in part because they just want to show off the building itself.

really, though, you can finish them like any other house; there's nothing special about the kitchen, bathroom, or walls that precludes it.

aside from the striping, i imagine there's not that much different about building internal structures into a house like this than there is into more traditional rammed earth housing.
