A prototype of an adobe house built by a civil organization called
Quetzalcoatl Center for Rural Development.
This house prototype is intended to serve as regular habitation for poor families. The design works good even in cold climates because of the low thermal conductivity of the material. Due to the fact that most of the building material comes from from the excavation for building the house the price can drop as low as USD$5K for a complete house like the one pictured here.
Cool, smart and good people is working on sustainable projects just
like this one: you can take action too!
