How would it react to an earthquake? Fire? Termites?

A standard Sollars Home™ is designed using reinforced high strength concrete. It’s strength and stiffness is derived from the fact that it is a single casting, which means that it has no inherent weak spots or joints and will perform better than a POWH in a quake. The concrete exoskeleton of a Sollars Home™ is impervious to termites, so it would be difficult to conceive of a situation where termites would be an issue. The concrete shell of a Sollars Home™ will not burn, but the interior wood frame and its contents will. Fire sprinklers are an option in a Sollars Home™.
