Through a series of studies such as interviews, we found that the village’s spontaneous development in the city gave the occupants the right to define the building freely. From the perspective of the building structure, we explore how to use parametric components and customized modules to build a variety of building units and make assumptions from residents’ self-issuance to bottom-up design, letting the participants decide for themselves. The function of the building is to meet the most basic needs of the individual inhabitants. The rest of the space and place can be interpreted as undefined shared spaces. This complex building is placed in the entire village of the city. 

In addition to the original self-built houses, the original buildings and modular components are harmonious, opening enclosure spaces and paths. This parametric component is determinable, low-cost, and extensible. We have used the original main roads to transform the abandoned buildings along the main streets and uninhabited buildings into parking spaces and green areas, creating a good walking and riding environment in the community as much as possible. The greenway is reconnected to stimulate the vitality of the site further.
