Also on the O.U.R Ecovillage was a Japanese inspired house that used rammed earth walls sitting on a rubble trench with woodchip/cement blocks for foundation.
The roof framing is classic Japanese crafted joints with mortise and tenon, and elaborate beams as you can see below.
There was an experienced Japanese craftsman who left a fine testament!
Here is the foundation, as mentioned, blocks were cast from a mix of wood chips in a cement matrix and then stacked.
I wonder how the blocks are connected to the rubble trench, is there any mechanical connection possible?
How did Frank Lloyd Wright do that in his Usonian houses?
The walls are made by pounding a straw/clay mix into a form, this way it is easier to build strong corners and complex stepped corners that you can see here.
Some detailing around windows and doors follows.
