The iron wood construction is prefabricated and assembled on-site, using bolts to ensure reasonable precision and strength. By raising the buildings from the ground, on four foundations cast in old tires, problems with moisture and rot in the construction are prevented. After a six month long mutual learning process with the locals in Noh Bo we hope that we have left something useful behind and brought important experiences into our coming projects. Important principles like bracing, material economization and moisture prevention may possibly lead to an even more sustainable building tradition for the Karen-people in the future.
