I am curious about the safe room, for tornadoes, right? What kind of door? How long are you provisioned for staying?
Battery power?
I see a few questions about our safe room/office. The plan here is to have a slab level tornado shelter. I'm almost 50 and plan on retiring and dying in this new house. When/if I get old, I want to be able to walk/roll/crawl into a shelter without going up or down stairs in my future old age. The door will be steel and rated for over 300 mph winds and debris. The door will come from the same contactor that will install the room. There will be a wooden door on the house side so that it appears to just be another bedroom or closet, when in fact, open the wooden door and there is a steel door behind it.
The office part just means that we will have our desk, PCs, paperwork, photo albums, etc stored in the room for security. The fiber optic feed from the phone company will land inside it. Phone and wifi will be on UPS. Also, all guns and ammo will be stored in this room. Basically, if we want to leave for the weekend, we can shut the steel door and lock, then shut the wooden door which will have two key-only deadbolts, and everything of any value in the house will be locked away. If someone wants to break in and get to any of it, it will take them a long time and lots of effort. Not saying it can't be done, but common thieves will not have the resources to breech it. There will be a small HVAC feed to the room. Under normal conditions, the steel door will be open and the air will return out under the wooden door. This will allow our Geo-Therm to control humidity which is important for gun/ammo storage. The room is currently 10'-11" x 12'-11". There will be some snacks and water and a few toiletry type items in the room. If a storm comes through and buries us in it, I wouldn't expect to be there more than 24 hours. I'm not a doomsday prepper....but there is no sense in not being prepared for something as simple as this. If you pour a 6" wall, you might as well pour an 8" wall.
The concrete ceiling also gives us a place in the attic to place all the geothermal equipment. The attic ladder will enter the attic space at the edge of it. So I can walk up the ladder right onto the concrete and walk around and service filters or whatever I need to do to our geo-therm all-in-on unit. No outside condenser. I think it will work out nicely.
