This post is already out of date, I'm afraid, my blogging isn't keeping up with construction! But for the last week or so we've had the slab of our ground floor!
There is radiant heat tubing in the floor, as well, but I was out of town and couldn't get the images before they were covered. You can see the end of the pex tubes, though.
I'll post more photos, soon, but they've already poured all the other site walls, and framing starts Monday!
