Alternative building process

I looked into some projects concerning the issue of alternative building process using sand. This diagrams are showing different approaches varying from Markus Keislers solar sinter, through the research of  bacteria turning sand into the sandstone by Mangus Larson and conceptual 3d printers. I felt like my solution could take some of properties of each of these processes. Ideally combine them into unique device moving through the landscape, solidifying some parts and create habitable space inside of solidified dunes. I would like to use wind which is moving masses of sand as part of my building process so the whole structure would evolve slowly in time.
