#Bioconstruccion or #Greenbuilding has more or less been captured by green capitalism in #Spain #España & is starting to look like a multi level marketing industry, not unlike how #permaculture has turned out.

Sand, clay, sticks stone , timber & #Tosca are plentiful on our land & were used extensively in the past.
