Walls and ... almost walls.

In the first floor (spare) bedroom:

A wall. 

In the upstairs bedroom / bathroom:

Almost a wall. 

So look at that second picture.  It's the master bathroom.  The window is above where the bathtub will be - see the framing on the log (exterior) wall?  The shower will be in the near corner.  And that area to the right of the bathroom?   Huge walk-in closet.  Yeah, baby.  I'll get some actual shots of that someday for you.  I mean, right now it's just empty space.  But it's a-gonna be a closet.  Oh yes it will.

Do you still have "The Final Countdown" in your head?   Ha!  It's nice to spread this insanity around a little.

Enjoy.
