With the development of technology and transportation along with economic growth, the industrial structure transformed from the industrial age era to the information age. As a result, in the industrial era, industrial facilities, which were the mainstream of transportation, production, transportation, storage, processing, and manufacturing, lost their original purposes and functions and became idle, and at the same time a phenomenon was observed in which they were abandoned in cities. These idle facilities undermined the aesthetic values of the city and has risen as a social problem, causing the decline of surrounding areas.
The term rhizome, derived from a botanical term, is a philosophical concept citing the rhizome of the arboreal system in Deleuze and Guattari's book 〈A Thousand Plateaus〉. The rhizome is open to all points, has no beginning, no end, and no center, and has the characteristic of making new connections. When these characteristics of rhizomes are applied to the regeneration space of idle facilities, the rhizome's characteristics are well shown in the complex facility, so that various spaces are connected while different, and it is possible to connect from one space to any other space. Through previous studies, it was confirmed that a rhizome analysis was conducted on shared space and public space, and considering that, among various spaces, the complex cultural space has similar characteristics to rhizome characteristics, it was confirmed that there is a relationship between the complex cultural space and rhizome. Nevertheless, research on the rhizome characteristics of the complex cultural space has not been actively conducted. Therefore, in this study, the rhizome characteristics appear in the regeneration spaces of idle facilities, and therefore, we intend to seek ways to utilize them as basic data.
By analyzing precedent studies related to rhizome characteristics, the characteristics of rhizomes were extracted, and rhizome characteristics were derived as connectivity, cohesiveness, diversity, non-hierarchy, and discontinuity.
First, connectivity means when two heterogeneous spaces are juxtaposed side by side, and second, connectivity is defined as a characteristic in which heterogeneous elements combine in plural. Third, non-hierarchical structure is when non-hierarchical and heterogeneous lines exchange and intersect in various directions and flows to have a plural and horizontal structure. In addition, all objects are not fixed, creating various configurations and possibilities and constantly changing. Fourth, due to variability, rhizome expands in various unpredictable directions, creating another manifold in the existing space or connecting to it to create a new composition. In addition, manifolds are defined that has neither a subject nor an object, and these entities are indefinitely connected to create events and actions to form various configurations. Lastly, discontinuity was defined as a characteristic that occurs when the position of the center continues to change according to the movement and actions of users.
Among the idle facilities using the regeneration space, the complex space is juxtaposed and connected, accessible from various points, and can be composed of multiple spaces. In addition, the characteristics of a space is shown in which users' actions can be freely performed. On the other hand, since the rhizome space has various and indeterminate paths due to the coincidental selection of users, and has a spatial structure that is individually juxtaposed side by side, it was possible to connect similar parts to the complex facility of the regeneration space using idle facilities and the rhizome characteristics of connectivity, cohesiveness, non-hierarchy, diversity, and discontinuity. Therefore, in terms of the rhizome, it is possible to interpret the space regenerated as an idle facility to suggest a direction.
In this study, among the regeneration spaces using idle facilities, the rhizome characteristics are reflected in the complex cultural space and the complex commercial space, and thus it is meaningful to provide basic data that can be referenced in space planning. Cases subject to analysis were analyzed based on cases opened within the last 5 years, and continuous additional research is required due to limitations in the number and scope of cases.
