It’s great that you are exploring alternative materials. We’ve just updated our Resources page where you can find the cost of building materials like brick and cement bags in Cambodian Riel.
Waste rocks from a mining operation are a potential building material if identified as fit for construction (i.e. will not pose health risks). Unfortunately, we don’t have any information about the mining company’s willingness to supply it to the local community or their waste management strategy.
Aside from the identified design considerations, keep in mind the existing skills of the locals in your building material selection.
We’ve also observed locals wearing sandals/flip-flops in most photos and videos. I found this helpful resource as to why that’s their preference.
