A continuous area or expanse which is free, available, or unoccupied.
The action of appropriating something; the deliberate reworking of images and styles from earlier, well-known works of art.
From space to place: An act of in-common appropriation is a powerful claim. It is about “marking a territory”  by setting up landmarks and boundaries in order to give a meaning to a space. According to many specialists, the appropriation process as a reciprocal exchange or “a mutually transformative process”  - which shapes both the place and the individual(s) - is central to the construction of the group itself  - as a social unity - as well as to the organization of its daily routine.
