This is the Shantikuthi earthbag spiral house,
a garden playroom at the
Peace Permaculture Garden in Nagano,
Japan. It was built by Michi-kun, a permaculturist and
carpenter with twenty volunteers.
The roof is arranged in a spiral where different plants are
grown for visitors to harvest seeds to take to their own
gardens. The walls sit on a 60cm deep
rubble trench foundation. Inside the house is a rocket
stove. You can see the construction steps in the video (above
right). |
