Interesting idea. What's the cost of this home vs a timber home? Life span, cost of upkeep, R factor, etc. From my observations building the frame of the house is relatively quick here in the states. I would be that the habitat for humanities groups could put up a similar size house frame in less than 8 hours. So what is the advantage here?
