Got a lot to go but we will get there. We did normal stuff on the kids part, the rest of the house will get some cooler stuff....

The block wall area inside the outside walls. Is that not what that is?What shelter do you speak of?
Sorry no explanation of pics. That's a hallway/entrance where my kid is standing by the block. Kids part is an old two car garage and was wood walls. I built every wall inside the new parts out of block closets, bath, kitchen bedroom and pantry. I forgot a footer under the office area (the hardwood part) so a small bath got light wood frame and drywall. Our bathroom shower will be the nado shelter. It's stout. Floor and ceiling is solid Crete.The block wall area inside the outside walls. Is that not what that is?
