The urban dweller is constantly seeking for new experiences, relationships and values, beyond the ones defined by conventional society. This need is the starting point for the formation of alternative intervention protocols. The most important distinction between the people participating in such interventions and an everyday citizen, is their active participation in a process of transformation of the perception of urban space.

Autonomy is a core element for these groups, as when in action, they are not limited to any social or spatial behaviour, thus forming new rules, radically different from traditional ones. These new urban «tribes», seek to affect the perception of the urban environment as well as the images produced and reproduced within it, through their action. Their aim is to demonstrate the issues that concerns them, maintaining, however a playful and relaxed behaviour.

These groups can be understood as a single element within the city, as they form together a system against the normality of the society. The idea of the formation of such a system, brings to mind the movement of the Situationists International. The Situationists identified similar issues to the structure of urban space, much like these groups, and tried to develop tools in order to overcome them.

The question the appears is whether or not architecture could evolve, around these groups, so as to develop new methods for reading and changing the city.
