The anti-Guédelon building

In the heart of Puisaye, in Burgundy, France a team of fifty people have taken on an extraordinary feat: to build a castle using the same techniques and materials used in the Middle Ages. 

In San Francisco, they are building a lego-resembling building. The techniques and materials are modern...

 

To be fair, the housing situation in SF is problematic to say the least... No time to waste.
