In Curitiba, Brazil, the municipality helped poor people build their own homes, one room at a time. Texas, having faced disaster after disaster, is using a similar model to get people back into their homes fast. There’s a core module with Kitchen, bath and bedroom, designed to be added onto as more funding becomes available. It’s called RAPIDO. Take a look. This could also be a response to affordable workforce housing.
One point in the video that sticks with me is the need to determine, long before a disaster happens, what the community would want to do with the funding that typically follows.
