I'm with you! Homes are still being built as food for termites and guaranteed to be dissolved by dry rot, mold and bugs! But out here in California, I wouldn't want a concrete home that would probably cave in, in an earthquake, and from what I remember of basements in the east coast, don't think I want a place for mold to grow! But I bet it won't be long until we start seeing a lot more composite materials that are stronger and more bug resistant show up. I guess metal beams are probably expensive, but I am replacing any wood on my home repairs with TREX and that concrete flooring for underneath ceramic tile instead of plywood. I'm also a big believer in the future of modular homes. Manufactured homes pre-made in the factory still are seen as less quality than conventional housing. But I remember going to the World's Fair up in Montreal back in 1967, I think, where they unveiled what I think was called Housing for Humanity, modular apartments that could be put together like legos. It's hard to believe that was seen as the future back then, is still not accepted, but I really believe that soon prefab homes, built with materials such as trex, will become the new way of addressing low cost housing and get back to simpler living.
