FAT Koehl Architekten's approach is taken from a vision where cities will become more social homogeneous with more moral values in the real estate profit standards to enable progress. The work in housing cooperatives or building societies dwelling, are intended to give shareholders the purchase of a dwelling in own or possess more of a dwelling by lease to prices and more favorable conditions than the market ones. To achieve this objective, the cooperative must make an housing project in all its phases: acquiring a building site, submit for the approval of a construction project, awarding prizes to a construction company and if you are the owner you can't sell it within a certain time period.
