The term ‘commons’ today is widely and extensively discussed within different theoretical frames of reference. Historically it refers to natural resources that we, the people, have in common. Resources that are not one’s property and are available to all: air, water, earth. Today, the term is used in very different ways in economic, social, and political theory, as well as within the creative industries. The project ‘Constructing the Commons’, initiated by the chair of Methods and Analysis of the Faculty of Architecture and the Built Environment of the Delft University of Technology at the occasion of the visiting professorship of Momoyo Kaijima and Yoshiharu Tsukamoto of the Tokyo-based architectural office Atelier Bow-Wow, investigates the commons from a tangible perspective, from an architectural point of view.
