"Quantify.

For example, the bunker "must withstand violent earth movement from severe earthquakes; high velocity wind from tornadoes and hurricanes; invasion by raiders or Zeds; heavy overpressure from nuclear blast; all types of radiation; wild fires and air contamination from any fallout and/or chemical-biological gasses in case the Zombie causing virus should prove to be airborne.""

"One important factor to consider when designing our future home is: What are we likely to be fighting? Most likely, we will be pitted against groups (from ones and twos up to dozens or hundreds at once) of infected, and also occasional packs of raiders. All of our defenses, therefore, must be designed to combat aggressive human attackers..."

"@ White76Knight -- My only concern stems from something I noticed when I looked at your profile: you own not a single firearm. With the right weapons I could transform even a sh!tty ground level apartment into a really difficult place for bad guys to penetrate. But with the tables turned, how well would you and your family fare in a fortress with high walls but no teeth? That would make it really hard for you to even pick off zeds, much less "aggressive human attackers." "

"Not saying you need the ratings for hurricanes and tornadoes specifically, but you need to quantify certain things.

Size of the bunker walls would be a good one. Space inside would be another. How are you recirculating the air?

As for close-ups, a Sketchup build would allow plenty of shots."
