Thanks a lot ! :D

• Minimum budget for humanitarian needs could be just some 2000 to 5000 $ (walls with earthbags or adobe or "giant 3D printing" methods, simple water and electric network, basic wind turbine).

• Then the budget for total autonomy could be 60 000 $ i think, because the builders have to add for energy a choosen mix between : 2kw wind turbine, 2kw photovoltaic , a solar cooker, rocket stove, thermal solar pannels, hydrogen efficient generator / with apropriate networks.

• The house in itself is really economic, since earth bags provide the best insulation, resistance (physic, climatic, earthquakes, tornados), for the only price of bags (1k€ for 1000 linear meters and 15cm thickness if i remember well). So the price will really depends on total autonomy needing (maybe in network with other houses, wich is the best solution following my researchs and plans) or not.
