Alternative homes are popping all over the world. The next example comes from Nagano, Japan. The earthbag house may seem like a building coming from fantasy novels, but it is a real place you can live in. The builder, Michi-kun, is an experienced carpenter and permaculturist. He got together 20 volunteers and began work on the inspiring home you can see in the pictures. The walls raised with bags of earth sit on a 60 cm-deep rubble trench foundation. The spiral house draws its name from the way the roof is arranged: in a spiral! There, various kinds of plants are grown. Thus, visitors and dwellers alike can harvest seeds to take to their own gardens. On the interior you can find a rocket stove and other basic furniture required for living simply and in connection with nature.
