Iraqi reed house neighborhood, built on a marsh."They made columns from the thick, giant rushes and gather 30-40 of them together to make pillars, and interweave them for a skeleton frame. They added reed mats, and even the decoration on the front of the homes is fancy lattice work made of the reeds. There's no glass, no nails, no wood." Even the islands the houses rest on are made of compacted mud and rushes.
