Abstract: Under a tight global economic working structure, it is hard to avoid centers and boundaries territorially and produce uneven dependent relationships between countries and places. Zoning regulations in modern cities often conjest many unusable segmental spaces and scatter across landscapes. In Taiwan, the dwellers would often use these spaces to recreate, they might be vegetable gardens, toolsheds and informal trading stands, and these behaviors is often acceptable by city council. Paracity is to take these phenomenon and response to another level. The sandbank between Taipei and New Taipei City has been in use and 'own' by roughly 20 people. Due to the rainy season in summer, the sandbank would disappear about 30 days, and therefore is not guided by urban zoning regulations. The project of Paracity is to build on such place and reuse waste of two cities for its water supplies and materials.   The agitated space remains after modernization, is Paracity would response. It attempted to bring them into a transformation, a statement of archaeology of knowledge. A series of paradox of urban development striated with many ruins, became a readable stratum of multiplicity. Here, Paracity is standing on a reterritorialization position, it is a Deleuze's Abstract machine of ideational event, turned to a living derivation of two-folds. Similarly, by Casagrande, these are 'pressure points' of living organism, the urban acupuncture is to serve these space and revitalized in all system. Paracity is a 'knowledge building', crisscross space point of unconscious of chaos, a virtual regime of signs as a regeneration of natural spaces to a natural organism. Paracity bifurcates genetic power on a knowledge building of assemblage of monads, engender of other dimension to deterritoralization.  This paper is focus on Casagrande Laboratory's latest design on 3rd generation city, as a vision of bigger scale compare to previous works. The design is the result of many researches of unique characteristics of Tamsui River which divided Taipei and New Taipei City. It further elaborates expansion of urban boundaries by Nomadology theory. It is the architecture without metaphor, an architecture representation of postindustrial era.
