2 Story Dome

This two story dome is built using earthbags, cob and trash bottles as the main building materials.

The earthbag dome is made of stacked courses of polypropylene bags filled with a mix of earth, sand and binder (cement for bottom courses and lime for top courses).

The earthbag dome is founded on a course of car tires filled with gravel. This foundation provides a solid footing for the dome while preventing any water infiltration via capillary action.
