My dad's company was building modular, stress-skin panel houses back in the 50s. They sold, shipped and constructed a bunch over to the Bahamas, like over 100. Those things went through multiple hurricanes and some were still standing last time I was there in the mid-90s. These were the old pre-fab houses, where the walls came in a container and the house was dried in within 1 day. Panels were thin plywood, heat glued and pressure formed to a honeycomb interior. Lightweight, cheap and unbelievably strong.
