You need only like 10 meters of concrete to stop any fire. Just build the houses inside.

I've seen fires skip valleys miles wide.

Are you suggesting we build houses inside concrete cubes with walls 10 m thick?

		I’m suggesting you don’t build them out of chemically treated wood that sparks into a blaze the moment a single ember lands on them. I don’t think that’s a very hard thing to do. I’d send you the blog post I read on the topic, but I can’t find it again :(
