skousen designs and consults on hardened retreat homes, often including fallout shelters with hepa air filtration systems. he has offered in both north and central america consultation regarding architectural and retreat design. in the book "dancing at armageddon: survivalism and chaos in modern times" by richard g. mitchell, jr., (2001) skousen was quoted: "'you never want to make a house look like an obvious fortress. those who want in can always move up a bigger gun. there is no way you can design a home to withstand rpg (rocket-propelled grenade) rockets and tanks. i design these homes so you virtually cannot tell inside or out that they are any different from a conventional home.'"
