This growth without design nevertheless results in organizational structures through processes of what I read as urban sedimentation.

A person can carry his home, business and transport on the body; and build up from there; several individuals create micro-organizations that, outside of legal structures, consolidate over time into complex systems creating the new urban matter of physical and social infrastructure. Matter is then understood as a network of interconnected parts that generate an entity made of related individuals, functioning at different scales at the same time.

For the Other Markets I am presenting several collages that present the case of micro-commerce, using typological diagrams made with photographic images that I have been collecting for several years in Lima, Peru, and Tijuana, Mexico. The visual diagram investigation is divided into four phases or typologies of growth:
