The rapid growth of cities process is causing the instability of large areas with heavy economic, social and environmental implications. Human settlements are called to deal with a growing variety of topics closely interconnected; planning and designing places need a multidisciplinary approach so that we can delineate a clear pattern of solving. In this International debate are inserted various opinions offering different methodological strategies, one of these is the "Metro Matrix" of Pedro Ortiz, which consists of a screen grid infrastructure around which to tie new urban centers capable of responding to the needs of the people through the provision of qualifying services.

The proposal metro-matrix in the city of Cairo hinges through the creation of 15 new urban centers: one of these, Ard al-Liwa, has been extensively studied in order to enter the urban and integrated metropolitan functions that bring welfare services within the site. A place is the result of the complex relationships that occur between its constituent elements and subsequent anthropological stratification: designing a place means decode the structural invariants then interpreting them projectually. From various readings, invariants able to resist in the long run emerged: the land parcels, irrigation channels, the trees and the axial topography. The relationships between these elements can be described by the set of landscape products from the decomposition and recomposition of the same within a unit of the figurative landscape. The next territorial analysis has revealed the hinge point of the Egyptian landscape able to withstand the change of scale in space and time. The concept of emergent system led throughout the second phase of our design process, in which, through an organic experiment it was generated a network hinged on "hinge point" identified by the anthropological reading that allowed the permeation of dense housing context. The organic nature of the network called "Physarum" emerged after a greater force diagonal axis compared to the consolidation of the context and were attested metropolitan functions of our centrality on it; from them the network capable of uniting both the metropolitan to the urban functions. All this is finally ended with a development of a metropolitan architecture designed to emphasize the elements identified by anthropological reading with cross-references to the settlement informal aesthetic such as the openings in the facade and underscore the slabs.
