Italian architects Diego D’Agostino and Enrica Papa have designed the Tomorrow Skyscraper in an effort to increase the quality of life for people living in the world's slums. The Tomorrow Skyscraper would be a prefabricated structure with housing units made of recycled materials.
The Tomorrow Structure would have units added and subtracted in accordance with demand. If the economic situation in a slum gets better then the building could be broken down and moved to another city or country. Check out the links to learn more.
