Subtopia reports on effective Red Cross/Red Crescent efforts to provide shelter to earthquake victims in Indonesia. Subtopia’s account is based on this report from Reliefweb:

“As part of the International Federation’s early recovery programme, more than 4,000 bamboo shelters have already been completed in the areas of Gantiwarno and Dlingo, and the programme is expanding into other districts, where up to 6,000 of the homes are expected to soon be built.”
After consulting survivors and enabling them to take direct responsibility for the distribution of funds and reconstruction materials, the program has resulted in a coordinated community activism to help survivors build shelters themselves out of local materials. [emphasis supplied]

And the shelters cost about $150 USD each.
