Current city planning contains an inherent dyschrony between the Urban Plan and the process. The first has been the usual instrument in the transformation of the territory based on economic, social and cultural issues that have been assumed to be stable and durable. The second, however, has operated as a factor of programmatic destabilization of what the Urban Plan had established as immutable and durable. Precisely, the definition of the urban refers to the unexpected, the surprising, the oscillating, the intermittent or the fluctuating and, therefore, opposed to any structural crystallization. However, beyond considering them antagonistic concepts, it is possible to conceive them in terms of complementarity through reuse processes that reinterpret the keys to temporality.

The experience of estonoesunsolar that activated temporary uses in abandoned lots allowed us to establish a methodology that linked all the factors involved in the temporary occupation process. This methodology was implemented in numerous public spaces. In the context of an evolution of these temporary occupation mechanisms, it is intended to extrapolate strategies for their application in the reuse of abandoned buildings.
