Before retiring as a professor of engineering at Cal Poly, I worked on a project in which we looked at materials, design, manufacturing, and construction costs of steel-framed vs. wood-framed structures. At the time of our efforts (circa 2001), the cost to frame in steel was about $1 per square foot more than traditional wood framing.
What did the owners get for their dollar? It turns out that they got a home or other structure that didn’t warp, rot, or become infested with termites; was electrically safer by providing frame grounding throughout, built of a material that was easily recyclable, and was virtually fireproof.
If we combine what we now know about steel framing with our local Hispanic heritage (white stucco walls and tile roofs) we come up with a way to build that may scorch and singe, but is essentially impossible to burn. Craftsman style and lots of external wood may look great architecturally, but these materials are simply a ticking fire bomb in Southern California.
As a Santa Barbara native, I have seen many wildfires burn in, around, and through our community. I always hope that each time it happens, we will learn how to prevent the tragic results of building unnecessarily flammable homes. Perhaps at least some of those re-building will now know that, for a minimal additional cost, they could re-build it right? — Mark A. Cooper, Ventura

I would think that, given a large and local enough fire, a house might still collapse, due to heat-fatigue of steel studs--of course the heat might still be deflected enough, by the mentioned tile and stucco. At the least, it would provide less fuel for such a fire. . . .
Monolithic dome homes are cool too, but they're kind of an acquired taste.

Is the material truly re-cycled? Or "down"-cycled, a much more common outcome for materials we consumers think we are "re-cycling". Down-cycled materials have more impurities (something that would be critical in a structural material) and are thus destined to be less usable than their progenitors.

According to the Wikipedia entry for "steel":
"Steel does not lose any of its inherent physical properties during the recycling process, and has drastically reduced energy and material requirements compared with refinement from iron ore."
I'm not sure if *any* true metal elements have an impurity issue for recycling, but is there a chemist in the house?
