Embryo Housing

Interesting concept. A blog post about a project in Chile that gets slum dwellers a very basic house, but one with services such as electric and sewer, which makes it a vast improvement over their current situation. What I find most interesting is what people start doing to improve this basic house once they have it. The original article is here, but I think the blog post has interesting ideas about formalization of slums, which he has written on before.
