Oakland fires long ago a guy built his home from limestone and metal etc ... but built a round silo sort of limestone tower on his property that had a 3000 or 20,000 gal water storage tank in the center with pumps and generators inside connected to a satellite phone controller.
Also had his in ground swimming pool plumbed as a reserve source of water for his well thought out redneck engineered system .
He had landscaped his property to keep fuel for wildfires away . As the fires approached he made the call to his “off grid” wildfire system and it was the lone structure that survived in that area.
Was impressed ......
