Just a little advice: First, put in an underground fire shelter about 20 feet down. There are companies out there which make very good ones from just the smaller shelters up to the kind one can live in for years if they had to and a couple of hundred thousand dollars added on to rebuilding is a small price to pay for the safety and security those things provide. Imagine simply going underground instead of evacuating to wait a fire out in comfort since one can get power generators as part of the deal. Build a monolithic dome home instead...
