Work on the concept of "hybrids" opens the way for the exploration of new theoretical operators through which the urban condition can be ‘attacked’ and some possibilities of breaking, at least hypothetically, with the fatal reproductive logic of contemporary settlements can be sought which go beyond tired replicas of existing formulas. From a design viewpoint one possible hybrid urban space might be defined as an even dissonant composition of architectural and urban spaces defined by the intersection of different types of spatial and functional forms or by the transformation of predefined spaces, according to a genetic and not deductive conception of the design operation. The concept of ‘urban hybrid’ works around the concept of ‘thresholds’ in the sense of an interval, network or set of thresholds. It acquires meaningfulness and that is it becomes a possible design intervention strategy that ‘inserts’ itself inside self-reproducing urban structures to identify an internal principle of regeneration, mingling and local hybridisation.
