Hi there and thanks for hsotins this Q&A session.

The soil in the region I plan to build on is all clay and it's not flat, so it has a potential to 'move'.
Do you see any way it could impact the building of an earthbag earthship?

Clay does expand and contract with moisture content, and the force of this action can be very destructive to buildings. It is generally advised to dig below any layers of heavy clay to avoid such uplifting. A rubble trench foundation can usually accomplish this. Any lateral expansion would need to be countered with strong walls and possibly back-filling with sand or gravel that drains well.
