Haitian Dirtbags

For the past week plus we've watched the nation of Haiti fall apart after an earthquake. Reading stories and seeing the images makes us very disappointed that we can't just up and go to help. But what would we do? We have no medical experience. We could help distribute supplies, I suppose. But since our passion is architecture, our thoughts leaned that way. Many people have lost their homes to the 7.0 rumbler. Even the presidential palace is destroyed (as in structurally unsound, not rubble on the ground).

Why did the homes fail? Mostly because of the poor building practices. A good number of homes are concrete with less than adequate mix and not necessarily any rebar. Concrete has the distinction of being inflexible. If you stress it, concrete does not bend, it cracks and breaks. Bad for homes.

So we gave some thought to how we could help the residents of Port-au-Prince. We thought about buying them some rebar, but shipping costs would be a bit high. We thought about designing some prefab homes ala Michael Janzen, but he's got a great product already and lumber is not exactly plentiful on the island.

So then we ran across some blog entries on earthbag homes. What is that, pray tell? Take a bag, fill it with dirt, stack, repeat. Easy. You can check out a Haitian Dirtbag home here that withstood the quake just fine. The owner of this home, Father Theo, cares for orphans in Haiti and runs a blog here. Their other concrete buildings sustained some minor damage. Think this might be a fluke? Check out some earthbag testing here.

"So what?" you might say. "This all looks fine. Are you going to go to Haiti and build earthbag homes?" Not quite. But we believe Father Theo is on to something. Earthbag homes use local materials, can be built in a day, are sturdy, insulative, and cheap. We would like to lobby with Habitat for Humanity to consider rebuilding Port-au-Prince with earthbag homes to avoid any future apocalyptic aftermaths. Once we get that okay, we will begin donating a portion of our plan sales towards buying bags, barbed wire, and any other necessities to rehabilitate Haiti.

You can voice your opinion too by clicking here. Please write and tell them that you think earthbag homes would be the most sustainable housing stock for Haitian revival. May Haiti thrive.
