We had walls, window wells, stairs and this crazy vapor barrier stuff that looked like a gummy tar substance.
I took a few close up pictures of this stuff and it actually came out kinda cool. I would have liked to see how they spayed it on. It was still viscous days later. We walked around looking to see if there were any gaps and we didn't see any.
We discovered building materials on the 26th. Trusses for the basement ceiling and the roof. At this time we had no idea what this was going to be used for.
