Informal Settlements
German Shantytowns

German architects no longer see settlements that are not planned and organize themselves as a problem, but rather as models. What exactly can German cities learn from them?
The centres of German cities are dying. Housing space is expensive and scarce, families are moving to the surrounding areas, people shop in shopping malls and come to the city only to work or sightsee. You find high-rise buildings in the centres as rarely as you do alternative, communal living concepts. Only those who have plenty of money can live directly in the centres; the remaining space is rented commercially or is in the hands of investors. In the centres of cities such as Caracas in Venezuela, on the other hand, life pulses. Symbolic of this is the Torre David: the residents use this house as they need it, without the permission of the authorities. They adapt the existing structure, a house without windows and plaster, to their needs. Here they live, learn and shop; here a self-organized system has emerged.
Architecture must thaw

Strengthen communities, make use of resources
A greater emphasis on responsibility also strengthens communities. The sociologist Richard Sennett describes how these new cooperations in societies in which planning is hierarchical have not yet been tried. “People need to develop skills to get along physically, and even more socially, with their neighbours.” In Medellin, Columbia, according to Sennett, communities have already moved in this direction. There, action groups are building libraries and hospitals. In Berlin, too, there are examples of community initiatives such as the former Urban Hospital, which is now a joint building project occupied by several groups, and the “Möckernkiez” (i.e., Möckern Hood) – but they are the exceptions.German cities and their architecture can learn much from developments in informal settlements so as to respond more flexibly to social changes. Perhaps German cities will soon be thinking of skyscrapers which previously housed companies and where now people from different social classes work and live. Or of communal and generation-linking housing complexes that are ecologically sustainable, inter-cultural and socially integrative.
