It's (almost) done. The contractors are finished, we've been able to use the semi-finished room for a couple of weeks, and the building permit is gone from the front window of my house.
But in order to save money, I'm doing some of the finishing work myself. Why pay the contractors to install a floor and paneling when I can do it myself (and take 10 times longer, curse more, and have it look almost as good as if it was done by professionals)?
(primed, not painted, so don't worry, it will look better soon)
The humans haven't been using the room to its full potential yet - we haven't even ordered the carpet, and walking around on the DRIcore subfloor barefoot isn't the best idea - but that hasn't stopped other family members from taking full advantage of the three walls of glass surrounded by birds and squirrels (and even an occasional chipmunk).
I've got to get one final coat of trim paint on the paneling, wait for the carpet to be installed, and I'll be done. And then it will be party time!
