STRATIFYING INFORMALITY 

HOW TO DENSIFY THE CITY IN LAYERS ? 

Project development for Master thesis ETH Zurich 

Cities always have been products of sedimentary processes. On the remains of old foundations new urban layers are erected according to new needs and modes of production. Informal cities are physical testimonials to this incremental process, in which old layers coexist with the new strata. "Stratifying the informal" means working with what is already there while introducing strategies to control densification. In this design approach "layers" are parameters derived from mapping and typology studies of the existing city fabric. A probable combination and permutation of these layers is what forms a city that is generated by transformative layers. By introducing specific building types to existing structures, vertical growth will be more directed, leaving open spaces for public use, light exposure, and ventilation. New formal layers are woven into the existing fabric, which ten activates a process of informal infills. The sedimented city is formed by constantly updating existing structures with new programs, technologies and building fragments.
