Emergency Dome fm 12 4x8 Plywood Sheets

This is a Dome that could be pre-cut and stored in a small space to be assembled quickly when needed.    !2 Ft Diameter and 7 Ft Tall

This partly depends on what the emergency is, so here are my thoughts:
1. It has to be stored somewhere, where you can be sure you can get to it in that emergency.
2. That "somewhere" needs to be where it won't deteriorate from the elements just sitting there.
3. One would need to make sure the hardware and tools were kept with it. (also, don't underestimate the quantity or cost of the hardware.)
4. They do mention using a tarp, or other options for waterproofing the outside. This is my biggest concern with this style of dome. They have a reputation for springing leaks.

In my ecosystem, I think I'd be happier building a proper storm shelter that doubled as storage of the things one might need in that emergency, such as sleeping bags, fresh water, and food storage. Dome shapes do stand up well in storms, but there are some systems such as blown concrete which is monolithic and thus more resistant to water infiltration.  

This plywood plan seems to me like something volunteers would procure parts and pre-cut, load on a truck and drive into the zone of the emergency and erect for the victims as first-in-place help.

How long did it take you to build that building?

How cost?

This is an interesting design--reminds me a lot of a wigwam, similar but made from different more natural materials, i.e. tree bark. It might be helpful to have the topmost panel be made slanted so that rain sheds from it outward instead of soaking in. It seems like an excellent thing for if you're caught unprepared in a disaster.

To me, I'd not want to live in it long term ideally... seems to me best to use natural materials (or make your plywood from cheese glue!) I'd want to set up a thatched hut, wigwam, or if I had the materials, a tipi or Mongolian yurt, things made from natural materials that have stood the test of time in harsh climates and inclement weather.

Also, you might want to make some kind of a scaffolding to keep it strong and sturdy in case a branch falls on it or something of the sort--maybe arch some saplings over the top to secure it in place, or frame it from the inside.
