A quick preview of how it might look

Unpainted, without corridor sections and with unfinished room tiles.  But if I waited until things were done I'd never post anything.



The room tiles need to be tested some more.  I thought they needed to be odd by odd for the corners and walls to work but now it seems like I need odd by even.  I have enough pieces I can test it and confirm.



Yes, I can see that the tops of the walls aren't going to line up perfectly.  I'm doing enough by sanding down the edges so they fit together smoothly.  Trying to get them all exactly the same height would have been well beyond my needs.
