My thesis focuses on Haibing public housing and the Pancah/Amis live there, revealing the social relations the inhabitants co-constructed with the material factors of the public housing. Indigenous people from eastern Taiwan have moved to urban areas in northern Taiwan since 1960s. Some of the Pangcah/Amis occupied the land on Bachimen, the peripheries of Keelung. With years of eviction and negotiation, residents reached an agreement on public housing project with the city government. Haibing public housing was completed in 1995, and most of the former residents moved in to the five-story apartments. Haibing public houing was born under different structural and institutional powers, including urban planning, public housing policy, and the governance on indegenious people. I focus on how these powers enact in substantial places. I analyze how the materialities of Haibing public housing was interwiving in the new social relations and the imaginaries of communities in three different aspects. First, I focus on households and the socio-materiality of home. Second, I analyze the heterogeneous network of human and non-human, which developed out from the planting/gathering patches around the public housing. Lastly, I focus on the urban illisin as a process of the production of locality, discussing the emergence of the imaginary of the community of "urban niyaro." With the results above, I argue that the material, spatial and institutional changes of public housing was interwiving and co-constructing with the social relations of the residents.
