local sustainable bldg materials and methods?

[Ccat]

I have been dealing with this here for thirty years.  There have been a small number of attempts in the state to produce locally sourced building materials.  I have tried to do this as well.  All attempts 

My own home has an engineered lifespan of 200-300 years and has a six hour fire rating and is 9x more resistant to earthquakes and hurricanes.  I built it myself for about $80 psf.  Most people I've met show no interest in anything beyond their own projected lifespan... which is too bad because it is not necessarily more expensive to build better it just takes a willingness to do things differently.  We have the technology.

so, please describe your method and materials.
