How much would it cost?

This is a part of our Cambodia forums to chat about anything Cambodia-related. This discussion forum is at the top of our site because it's usually the busiest part of the expat community chatter with random topics on just about everything, including expat life, Khmer politics, Cambodian blogs we have or have come across, or whatever else our members want to discuss. Whether you're an expatriate, tourist, Cambodian or random traveler just passing through South East Asia, you are welcome to talk about anything or start new topics yourselves.

Check out earthbag homes using rice hulls after the first few coarses of earth.
"Earthbags have the tremendous advantage of providing either thermal mass or insulation, depending on what the bags are filled with. When filled with soil they provide thermal mass, but when filled with lighter weight materials, such as crushed volcanic stone, perlite, vermiculite, or rice hulls, they provide insulation. The bags can even act as natural non-wicking, somewhat insulated foundations when they are filled with gravel."
The walls are then cemented just like the typical khmer brick building accept the walls are 18" thick full of insulation.

This has been a really interesting thread. I am almost tempted to build again. Would fancy doing a place on stilts with solar panels, passive cooling etc.
I wonder whether rammed earth with an outer protective skin/barrier would work in the tropics as well as it does in dry heat environments for passive cooling. Or, same concept, burrows like Hobbit houses.
Adobe?

You're asking if adobe = rammed earth? No, it's a little different in that rammed earth is compacted into standing molds - that is, you build a mold for a wall and then progressively pack and compress substrate into it. The compaction is the key, turns out to be very dense and a good insulator.

Cambodia,,,, Don't fall in love with her.
Like the spoilt child she is, she will not be happy till she destroys herself from within and breaks your heart.

Quite liked the open brick idea around the ground level area tbh.
No matter how much it rains, the dirt never washes away.

Rammed earth is a much drier mix and can contain a little cement to make it hold, it's the compression that gives it it's properties.

It looks great, and you could screen it in with flyscreen so it's a useful area at night, too.
