Structural information is piling up for contained earth. But few people know about what is proven or what seems likely.

Engineers and architects need easy access to technical data. And we need input from engineers willing to get their hands dirty with natural building. 

Good soils and better details create buildings head and shoulders above the ordinary earthbag crowd. In seismic risk areas that will be- literally- a lifesaver. We don’t have the unified theory of the cosmos yet. But we’ll share our glimpses.

Builders, tell your engineer and designer friends to check out our new site at We’ll be letting a bunch of engineering cats out of a bunch of bags. The chase should be productive.

Ultimate goal: simple guidelines so more earthbag and other natural buildings can survive earthquakes!
