Quonset Hut

I have been looking into Quonset-type huts as a relatively inexpensive shelter both during and after the pole shift. There are quite a few websites dealing with storage buildings, but I was particularly looking for dome-type design. They would be cemented into a floor pad several inches deep. Size varies enormously, and there are many suggestions for uses aside from equipment storage. I'll include the website I've been looking at:

www.conservatek.com/

Of these three, the conservatek is quite similar to geodesic dome,only made out of aluminum - bonus for firestorms!
