パブリックスペースにおける滞留者を疎外するDefensive Architectureの不認知化の実態と要因

―都内3繫華街のワークショップを通した滞留行為を阻む空間要素の抽出から―

This research focuses on the Defensive Architecture(DA), which prevents people from staying in public spaces, and collects and categorizes them through workshops. The first WS revealed the presence of 21 different DAs. The second WS defined the “depth of nonrecognition” and the 21 DAs were divided into 6 stages. Furthermore, the field survey revealed that there are three types of Defensive Environments with spatial extents in which multiple DAs act to alienate squatters. The study of “Defensive Architecture” is a good clue for us to think about how to use public space.
