That is a *brilliant* interior! I can tell that a lot of work went into it.
One question: did you paint the interior walls prior to assembly, or after assembly?
I ask because I've come to the conclusion that I have to finish the interior detailing of the walls prior to assembly, if only because it's so difficult to paint stuff on the inside. The furniture can be painted and then inserted (loose, or glued down) but not the walls, window frames and so on.
Great job, and great furniture!
