I'll bite. Why do you think a domed home would take less damage? A twister will damage that home as easily as any other, unless it's a concrete dome. Even then it's gonna take damage but somewhat less than traditional stick built.

I've performed search and rescue on multiple tornado responses and the amount and type of damage would have you scratching your head. I've seen lumber driven into and through concrete and trees. I've seen the wind get under a very solid structure and lift it off it's foundation. You simply don't know what a tornado will throw into your home.

Cost would be probably the biggest issue and when weighed against the chances of actually being in the direct path of one, it's simply not worth it when you can install a bunker and keep your insurance paid up.

I’ve seen pine straw driven through 3/8 steel and hickory trees. It’s crazy what big one will do

Build your home in the shape of a Toilet. I've seen many Pics where that is all that's left on a Slab home...LOL!!

There’s probably only a few companies out there building these. Anything that’s fairly unusual like that likely has peculiarities that can be problems later on until enough people have built them and figured out the learning curve. I’ve heard the ICF homes are probably going to become more and more common and affordable in the near future and I’d definitely be interested in one when there are more contractors building them.

I helped fix a house in Arab in 2011. When a telephone pole comes through your house at 200mph it doesn’t matter what shape it is.

They’re fugly for sure…but as stated earlier, 500 bricks from the houses a half mile away that are flying 200+ mph, simply won’t fly over the dome structure.

It may not even have sheet rock on the interior . Who knows? However, squaring up and framing the inside like a conventional house would be costly and a loss of square footage . Think square peg in a round hole. When building, anything unconventional , aka "out of ordinary", almost always cost more.

Oh yeah, it's hideous !

I built a 12x12 in ground storm shelter with 12” blocks concrete floor an 10 “ concrete top . I hope it can get fema approved for the tax break . All I need is a custom metal door

It may have changed, but I did that on my last home. And found out after the fact FEMA has to approve it BEFORE you build it or they won't reimburse you.

I remember this house built in Plainview, Tx. The Atomitat House.

I lived in Springfield Missouri as a teenager. Been through a few tornadoes. Seen a 2x4 stuck in a tree and another time I saw one side of a street almost completely destroyed while the other side barely had any damage. Tornadoes aren't fun at all. I'll take a Hurricane any day.
