Traditional system of social ties and communities, based to a major extent on the classic dichotomy of Gemeinschaft/Gesellschaft succumbs to the process of debilitation, even atrophy. Modern social networks are undergoing a metamorphosis towards the system of “weak ties”, the term coined by Mark Granovetter. Those ties, despite their name, are very effective. Changes in the social sphere are dynamically connected with the process of redevelopment of urban spaces. The spaces evolve towards creation of residential complexes that enable an unlimited choice of living scenarios and lifestyles (Homo eligens [choosing agent] architecture). The trend towards pluralism is connected with the tendencies to create multicultural spaces, that evolve in the direction of becoming transnational.
