Wednesday again, and again help from Martijn. We took out more sand so the foundation was free all around the room. Then when I wanted to show how thick the insulation material is I found next to the garage, there was a nice surprise, all the plates of insulation material where still frozen together. So there was not so much need to start digging more, as we could not try the insulation material anyway, so we decided to strip down the last wall and ceiling covering down to the bare wood, so the room would be ready for the building up part. And poof, another day was gone.
