The project is based on the visual presence of grids in the distribution of space in a social group: the planning of urban spaces, the division of one space into rooms with different functions, the mapping of streets with navigation markings, the placement of borders and barriers, permissions and prohibitions. Grids resemble a "semi-permeable membrane" analogous to that of cells - they divide the space, which becomes accessible to some and inaccessible to others, yet primarily they contribute to an illusion of inaccessibility and separation. There is only one space, but language allows for plurals because of the imposed parcelling convention. In this sense, the reference to grids is a reference to the "intersubjective narratives" attached to them, not so much to their formal characteristics. "Machine à habiter" is a phrase used by architect Le Corbusier in the 1920s to describe his idea of a functional house unit as a "machine for living in".
