Is it possible to create a system by which you could mass produce inexpensive, lego-like homes for those who currently live in slums?
Would it be possible to mass produce houses using a lego-like building method? You could slot metal/plastic bricks together to make cheap houses for those who live in slums. The bricks could have electrical wires, plastic water pipes, central heating etc. running through them to save time for fitting utilities together, saving the cost of hiring building professionals.
It would also need to work in such a way that expensive foundations would not be needed, just a flat surface to build on.
