The contemporary city requires sustainability and self-sufficiency for various reasons. Understanding the city as a “reciprocal spontaneous constitution” would be able to resolve those demands. Since contemporary society has been evolving with exchanges of matter, material and immaterial, within various man-made systems—social, political, economic, or technical—established throughout human history, living in the contemporary city entails simultaneously experiencing as well as engendering a multiplicity of these exchanges. An intricate multiplicity of contemporary society is evolving, progressing, and reproducing through mutual communication. It impacts the physical structures of a city; from small houses to huge urban infrastructures; from individual gardens to public spaces. Therefore, the contemporary city should be understood through reciprocal relations among multiplicities beyond multiplicity itself. In general, the phenomenon of reciprocity defines a potential property from which entirely new individuals with new characters can be created when various individuals with different attributes relate to each other comprehensively and elastically. For instance, on a smaller scale, a deformed root of a tree along a sidewalk disrupts the pavers and creates a new pattern. Or an abandoned structure transformed by gravity and a long period of neglect on a larger scale. Those conditions can be found everywhere in the city. Understanding the concept of reciprocity begins with accepting the dialectical nature of every single existence. By embracing the dialectical nature of beings, i.e., natural and artificial; matter and nonmatter; majority and minority, plural interdisciplinary networks begin and at last, a new paradigm can be conceptualized beyond duality and plurality. The reciprocity would characterize a city, the field of everyday life, and make the city alive and sustainable.
The purpose of my trip was not only to explore reciprocal phenomena in the contemporary metropolis by traveling through two representative cities, Berlin and Shanghai, but also to verify the reciprocity for developing a contemporary city and its architecture. Although Berlin and Shanghai are contradictory cities in terms of their sociocultural, economic, and political backgrounds, both cities hit a great turning point after major political changes in the 1990s. The cities have been redeveloping their urban fabrics so far on their own demands. It had been aimed not only to express the cities’ new optimistic paradigm for the future but also to reflect people’s new daily routines, which had been directly impacted by those sociopolitical changes. In the case of Berlin, the city’s main interest was how the city’s original structure, with its great history, could be restored and reborn as one capital city of Germany. With the dramatic history of modern Germany, the city and cityscape had been changing continuously and radically, furthermore, after the historic and symbolic reunification of Germany, around 45 km of long empty fields between the former Berlin walls have been filled with new buildings and landscapes. As a result, almost half of the city has been replaced with new ones based on the city’s master plan for 2020. The contemplative efforts to restore Berlin have been achieved by multiple parties such as architects, planners, the government, and even small local committees, and they are still arguing and working together to modify the city’s master plan for a better solution. On the other hand, developing Shanghai has been led by a strong central municipal policy. Funded by foreign investments and encouraged by local and central government, it has been moving forward without any barriers. New buildings, infrastructures, and public spaces in Shanghai comprise the second largest period of urban transformation in China’s history after the Qing Dynasty, affecting the country’s social, political, cultural, and economic spheres. While Berlin has focused on restoring the city and complying with its original character, Shanghai’s major issue was to expand the city not only to maintain the significant increase in population but to create a showcase of China’s symbolic future. The city also required redevelopment of underdeveloped areas in the city. Although both cities have different backgrounds and developing stories, both have been challenged to develop while incorporating existing urban fabrics in a reciprocal way.
Every snapshot in this report is a record of reciprocal phenomena in both cities. They show unique strategies for redeveloping the city within its traditional and historical legacy and shaping new paradigms for the city’s future and for the lives of its residents.
