I just stumbled into this...
Open Building Institute: Eco Building Toolkit
It's from Marcin Jakubowski. If you're not familiar with him, he spoke at PV2, and he's the guy behind
Open Source Ecology.
Apparently, he's branching out into construction, with the goal of creating a simple modular building system, based on local materials, allowing construction of a 700sf home for less than $25,000 in materials. While I don't think that size/cost is unprecedented, his goals for making this accessible are impressive, and locally manufacturing all components (think glazing, insulation, etc.) is downright ambitious.
I'm not sure this is the right forum for this, but I'm not sure what's a better one. Feel free to move if appropriate.
