Well, the progress continues - along with some changes.  We're not sure why we didn't think of this much sooner but the plan now is to make the upstairs loft the master suite (Thanks Doug!).  It threw the momentum off for a couple of days but the guys are back and on track!  The first photo is a partial view from the upstairs, then there is a view of the master suite from the top of the stairs, and then the south wall gets its own Tyvek suit (since our Parvo outbreak at work, it's the same thing we wear when cleaning and handling sick litters)!
