Door

The Burgundy room en-suite has a door! 

Not yet in a conventional location, mind you.

Getting a sliding door to fit precisely proved to be something of a challenge.  There are now more holes in the wall than there should be - though they are covered up by the support timber, which also has more holes in than there should be - though they in turn are covered up by the sliding gear metalwork (which, has fewer holes than the instructions say fit screws into, so I guess that's some form of balance).
