In those areas in which unauthorized construction is widespread, informal phenomena are a tangible manifestation of the social relationship with built environment. Structural or decorative elements are figured out and crafted to quickly respond to two important needs: spatial appropriation and self-representation of the builder. Those elements adapt their form to any concrete frame constructions and the modus operandi of the builders; absorb imperfections; speed up work; recycle existing materials.
SPONTANEOUS project, starting with an international call for drawings, would study and understand those elements to trigger a new idea of context, that is economical, social and geographical, where architecture practice should implement this need for customization.

An informal architectural element, widely employed in a community, becomes an important subject of design interest; implementing new design process, responsive to immediate needs, to meet higher aesthetic and safety standards.
