Our proposal defines SIDAREC Center as an infrastructure for the slum’s artistic, cultural, and functional expression. All the building spaces will be defined by a system of blank fences that users can appropriate as they see fit. Slums can show a poignant sense of fragility and adaptability that has inspired us in the design of our fencing system. The proposed fences do not fit exactly in the underlying hexagonal grid; rather, the system is designed with some tolerance in an attempt to overcome potential problems such as the impossibility to obtain the right material or the lack of good labor. As a result, and as the plan of our design shows, the proposed fencing system is delicate yet with a strong character, exhibiting an image that we find appropriate and inspiring for SIDAREC’s mission.
